Large-deformation analysis of nonlinear elastic fluids

Prost-Domasky, S.A. (Department of Mechanical Engineering, Washington University); Szabo, B.A.; Zahalak, G.I. Source: Computers and Structures, v 64, n 5-6, September, 1997, p 1281-1290

Abstract: A computational analysis was undertaken of four nonlinear generalizations of the simple Maxwell viscoelastic fluid under conditions of large deformations. The four fluids are named the upper convected Maxwell, lower convected Maxwell, Jaumann and Dong-Skalak-Sung fluids. Each of them is characterized by two material parameters, a shear modulus and a time constant and each reduces to the simple Maxwell fluid in the case of small, slow deformations. The finite element program ADINA was adapted to compute the mechanical responses of these materials to imposed surface displacements of various types. Our algorithm was based on the equality (for an incompressible material) of the components of the second Piola-Kirchhoff stress with respect to material coordinates and those of the Cauchy stress with respect to convected coordinates. After evaluating the algorithm's accuracy with respect to a limited set of available analytic solutions, the responses to indentation by a rigid, sharp-edged cylinder of a half-space composed of each of the four nonlinear fluids were computed. These calculations included a wide range of indentation speeds, covering the spectrum of material behavior from viscous fluid to hyperelastic solid. The computations admitted large indentations - up to six indenter radii in special cases. In contrast to their radically different behaviors when subjected to large homogeneous deformations, all four materials exhibited similar behaviors when subjected to deep indentations. For any specific choice of material and computational parameters, the computation terminated if the indentation became too deep and the magnitude of this maximum achievable indentation depth decreased with increasing mesh refinement. 1997 Elsevier Science Ltd.

Numerical simulation of a BWR vessel lower head with penetration subjected to a postulated core damage accident

D. Azodi and P. Gruner

Gesellschaft für Anlagen und Reaktorsicherheit (GRS) mBH, Germany

Transactions of the 14th International Conf. on Structural Mechanics in Reactor Technology (SMiRT), 1997

Abstract: To assess the safety and the integrity of nuclear power plants in operation, hypothetical accidental events are considered, which – on account of their low frequency of occurrence – do not belong to design accidents. In this context, a global finite element (FE) model of a German BWR RPV lower head and a control rod nozzle was developed. The melt down time estimations were obtained by FE calculations of the temperature distributions, which consider the influence of the complex heat transfer into the RPV lower head and control rod nozzle as well as phase changing of steel material.

Abstract: The project CORVIS (Corium Reactor Vessel Interaction Studies) is a research programme for the experimental and analytical investigation of a possible failure of the pressure vessel of a light water reactor during an assumed core melt accident. The applied methods of the experimental technique, the metallurgical investigations and the computational analysis are described. Two recent melting experiments are presented in detail. The first experiment was carried out on a steel plate 100 mm thick representing a pressure vessel lower head without penetrations. The second experiment was performed on a steel plate of the same thickness but representing a boiling water reactor lower head carrying a tube penetration in the form of a drain line. Reported are the phenomenology of these experiments, the results of the metallurgical post-test examinations and the computational reconstruction of the observed heat transfer and ablation phenomena in a stagnant and in a turbulent melt. Further, the results of three earlier tests, on a smaller scale, are presented.

A.R. Massih, K. Forsberg and L. Plobeck

ABB Atom, Sweden

Proc. 14th Int. Conf. Reactor Technology (SMiRT 14), 1997

Abstract: In this paper we analyze the dynamic response of a circular cylinder in a cross flow using the wake oscillator model of Iwan and Blevins. We solve the nonlinear differential equation for the considered system utilizing both full numerical solution and an efficient algebraic analytical solution. In the latter we have approximated the displacement of the tube by truncated trigonometric series for which the resulting algebraic equations for the coefficients in the series provide a straightforward numerical solution for the amplitude of the oscillation versus the flow velocity. Our results are discussed in light of available experimental data. Lastly the computational fluid dynamics computer code ADINA-F is used to study the fluid structure interaction behavior of the system under consideration.

Abstract: This paper focuses on the development of advanced fuel elements for innovative pressure tube light water reactors. Considerations and constraints that affect the design process and various possible options are discussed. The two most promising fuel designs, which can survive a loss-of-coolant accident without primary coolant replenishment, while having sufficient margins to fuel design limits, are proposed, described and evaluated. It is demonstrated that this key objective can be achieved, provided that reliable SiC cladding or coating, which can withstand operating and accident conditions without failure, can be manufactured. Recent advances in ceramic coating technologies and experimental tests of coated specimens indicate that the attainment of this goal is feasible.

Publisher: Elsevier Ltd

Abstract: Several techniques of lumbar disk annulotomy have been described in clinical reports, but have not addressed the influence of annulotomy type on motion-segment stability. The technique used to incise during diskectomy may play a role in the subsequent healing and biomechanical stability of the disk. The purpose of this study is to develop a finite-element model using ADINA to study the influence of annulotomy-technique selection on disk competence. The analyses showed that both the box- and slit-type annular incisions produced similar changes in the biomechanical characteristics of the disk excepting the stresses in the disk annulus. The study also showed that there is no preference between the two annular incisions as far as post-surgical stability of the disk is concerned. © 1997 Elsevier Science Ltd. (14 refs.)

Publisher: American Concrete Inst

Abstract: This paper presents details of an experimental and numerical study of thermal strains and induced stresses in large-scale mass concrete. Three large-scale monoliths were built on a dam construction site in the James Bay Territory to monitor the thermal behavior of mass concrete subjected first to heat of hydration development and subsequent freeze and thaw cycles. The monoliths were instrumented with thermocouples and mechanical strain gages. The modeling of one monolith was carried out with computer program ADINA. The modeling includes the development of a heat of hydration curve typical to the concrete used in dam construction. The mechanical properties of early-age concrete were based on measurements or evaluated from various references. It is shown that, due to an inadequate representation of the reference temperature, many nonlinear incremental commercial software cannot correctly simulate the stress history of maturing concrete with the temperature variation. The paper presents a modified step-by-step approach which improved the stress modeling within the available commercial software. Excellent agreement between measured and computed temperatures and stresses was obtained. (10 refs.)

Abstract: A dynamic elasto-plastic large displacement response analysis of the bottom floor of a generic vehicle hull model subjected to empirically obtained coupled blast and impact loads has been conducted using 3-D shell elements in the ADINA nonlinear dynamic finite-element analysis code. Although several simplifying assumptions are made regarding the structural model, material properties, and forcing functions, the investigation gives valuable insight into the nonlinear dynamic response behavior of a generic hull bottom floor to externally applied coupled blast and impact loads and provides an inexpensive method of evaluation of the structural integrity of modern vehicles subjected to spatially varying transient loads.

Publisher: China Welding

Abstract: The J integral parameter and its application feasibility in welded joints with different weldmatchings in yield strength (overmatching weld and undermatching weld), different material constitutive laws (material with a Ludes yield plateau and power hardening) and under different fracture types (ligament yielding fracture and general yielding fracture) are investigated. First the condition of J integral path independent has been studied based upon finite element analysis by using ADINA procedure on welded joints. It was shown that the J integral is path dependent for the cases studied in this paper. Then experiments were carried out to study availability of J integral as a plastic singularity parameter at the tip of the notch in welded joints. The results show that J dominance in most cases studied is not validated in v and u displacement fields. From both considerations mentioned above it can be concluded that J-integral as controlling parameter used to estimate the safety of welded structures is not always made clear. (3 refs.)

Abstract: An elasto-plastic constitutive model developed by the authors has been further extended and implemented into a user-supplied material model in conjunction with a commercial Finite Element Model (FEM) code, ADINA. As benchmark problems, comprehensive experimental data by Jiang and Sehitoglu (1994a,b) are compared with the numerical predictions of the model as implemented in the ADINA code.

Abstract: Spillway Tainter gate No.3 failed at Folsom Dam, CA, on July 17, 1995, resulting in a discharge of 1,132 m3/s into the lower American River. The gate is one of five service spillway gates 12.8 m wide by 15.2 m high. There are also three other emergency spillway gates, with the same width, but 15.9 m high. An action team was first established comprising personnel from the US Army Corps of Engineers and the Bureau of Reclamation to design reinforcements for the remaining seven gates, and to design a new gate to replace the failed one. Because of the importance of determining the actual failure mode, a forensic team is formed which turned into a multi-disciplinary, multi-agency team which were found to be a very good decision.

Abstract: The non-linear dynamic response of concrete gravity dams under seismic loads is a little-understood phenomenon due to limitations in the previous studies. The choice of a reliable concrete constitutive model and constitutive parameters to predict the performance of concrete gravity dams under severe earthquake ground motion is one of the most complex tasks. The response of a typical medium-height concrete gravity dam to a realistic motion is examined using the ADINA concrete model. The fracture energy cracking criterion is applied to remove the unreasonable mesh sensitivity of the results. The influence of the constitutive oarameters on the earthquake response analysis of concrete gravity dams is also discussed.

Abstract: The time-dependent thermomechanical behavior of a silicon-carbide-fiber reinforced titanium-aluminide matrix composite systems and the residual stress state developed upon cooldown which initiates matrix cracking, was investigated using a three-dimensional model. However, based on the information gained from the three-dimensional model, it was concluded that an axisymmetric two-dimensional model would be sufficient and computationally more efficient. Contact surfaces were used to model the fiber matrix interface. The use of the contact option to model the fiber/matrix interface assumes that the bonding of the fiber to the matrix was a consequence of mechanical bonding only called weak bonding. (3 refs.)

Abstract: This paper deals with the investigations of temperature distribution during vacuum brazing of cylindric Al2O3 and steel samples, using the AgCuInTi active filler metal. The thermovision system AGA 680S was used to register the temperature field during brazing cycle. Bonded joints were observed by the infrared scanner unit during heating, brazing and cooling. Two types of joints with different shape of steel element were examined during temperature measurements. Additionally, a 2D finite element code 'ADINA-T' was used to solve for the problem of nonlinear transient thermal analysis of temperature distribution in the axisymmetric models of Al2O3-steel brazed joints. The experimental results revealed the presence of big transient axial temperature drops in the ceramic part. The change of metal shape resulted in a reduction of the transient temperature drops in the ceramic element. The finite element calculations corresponded well with the results of measurements and showed that the perfect thermal contact between adjacent surfaces plays the important role in heat transfer and can be a factor affecting temperature gradients in ceramic.

Abstract: The response of masonry arch bridges to moving wheel loads was simulated in the laboratory by constructing four half-scale arches with a span length of 1.22 m, using 17 voussoirs and lime mortar joints. The moving loads varied from 115 kg to 910 kg and were simulated by hanging steel weights from the center-of-gravity of the voussoirs. The finite element program ADINA was used to model the arch ring using 13,312 8-node isoparametric elements. Experimental results show the lime mortar joints exhibit significant plastic deformation accumulations with the first few cycles of loading, then diminish during subsequent load cycles. When the Drucker-Prager material model is used for the lime mortar, the FEM results indicate the plastic accumulations do not occur after the first load cycle. It is believed that sliding occurs between the voussoirs and the mortar, producing small cyclical deformations under moving loads. The four arches were also monotonically loaded to collapse in the laboratory, and the FEM stress variations normal to the mortar joints are illustrated for this loading condition. (7 refs.)
