Analysis of high-temperature behaviour of solidified material within a continuous casting machine

Boehmer, J.R. (Univ of Siegen); Fett, F.N.; Funk, G. Source: Computers and Structures, v 47, n 4-5, Jun 3, 1993, Nonlinear Finite Element and ADINA, p 683-698

Abstract: The continuous casting of metals is determined by a multitude of degrees of freedom, the combination of which conditions the quality of the products. To investigate in a theoretical way the principal possibilities that influence the process, an analysis is performed to simulate the high-temperature behaviour of the solidified material within the continuous casting machine, i.e. within the mould (with respect to contact and shrink gap formation) and the following secondary cooling zone (regarding support rolls and spray cooling). For the simulation of mass transport, solidification and/or remelting, and heat transfer, a finite difference method is applied; for the calculation of the thermomechanical stresses and strains the ADINA program is used as a finite element method. Both thermal and stress analysis have been iteratively coupled to consider feedback. Emphasis is put on the highly nonlinear material behaviour at temperatures near the solidification temperature as well as on the three-dimensional and transient contact between strand and mould. To guarantee both accuracy and effectiveness of computation, there is need for a problem-specific discretization, load history and stress-state formulation, material modelling, and coupling strategy.

Conference: Proceedings of the 9th ADINA Conference, Jun 23-25 1993, Cambridge, MA, USA

Abstract: In this study, a method to evaluate sensitivities in post-buckling analysis is developed. The gradients of load values obtained under several constraint conditions are discussed. Unlike other methods for sensitivity analysis, the present method can cope with both snap-through and bifurcation problems without eigenvalue analysis. In addition, the load sensitivity at arbitrary points on an equilibrium path can be calculated. Using the MITC4 shell element, several numerical examples, such as a bifurcation buckling and a snap-through analysis of shell structures, are solved to show the performance of this sensitivity analysis method.

Abstract: IRM (Intergraph Rand-Micas) is a finite element analysis package of the Intergraph CAD system. The IRM neutral file translator is a module which allows the user to create an ASCII file from an IRM model or read a properly formatted ASCII file to produce an IRM model. The ASCII file contains all the necessary information defining the finite element model (node coordinates, element connectivity, loads, etc.). The other finite element analysis systems such as ADINA, NASTRAN, ANSYS, etc. can use the information of the IRM neutral file provided that the data have been converted properly by a conversion program. INTOAD has been developed to do this. In this paper the contents of an IRM neutral file are briefly presented, the main differences between IRM and ADINA are outlined and the development strategies of the program INTOAD are described in detail.

Analysis of welding-induced residual stresses with the ADINA system

Conference: Proceedings of the 9th ADINA Conference, Jun 23-25 1993, Cambridge, MA, USA

Abstract: The welding-induced residual stresses analysis procedure (WIRSAP), based on the ADINA system of nonlinear finite element software, is described and the results of several WIRSAP analyses are discussed. Several two-dimensional (2D) axisymmetric WIRSAP analyses have been performed for pipe girth welds and for several multi-pass girth-like welds attaching small nozzles to large, thick-walled pressure vessels. The analytical methodology follows closely the basic techniques outlined by Rybicki et al., enhanced by the use of several specialized modeling techniques available in the ADINA system. For example, the element birth option is used to simulate the addition of weld metal, and the mixed pressure/displacement element formulation is used, in conjunction with the temperature-dependent bi-linear plasticity material model. Some of the welds analyzed involve backing rings, which were subsequently `machined off' via use of the element death option. The auto-time-stepping algorithm and the matrix update iteration scheme are used in the structural solutions. WIRSAP involves, in general, a pass-by-pass analysis of the uncoupled thermal and structural problems, but some analyses have been performed with an `enveloping' technique for grouping several weld passes together to study the feasibility of modeling multi-pass welds on a layer-by-layer basis. The analyses discussed here are all 2D, but most are large problems (gt;5000 nodes and gt;5000 four-noded elements, with a large number of solution steps). As such, they pose significant challenges to both software and hardware resources. Pre- and post-processing operations are performed on a network of Silicon Graphics workstations, and ADINA and ADINA-T are executed on a 64 MW, eight-processor CRAY Y/MP. Nominally 50 solution steps are utilized for each weld pass, and weld joints involving as many as 31 individual weld passes have been analyzed on a pass-by-pass basis. Results from several of these WIRSAP analyses are discussed, and the potential use of WIRSAP in a hypothetic attachment weld design optimization study is illustrated. (17 refs.)

Abstract: The response of the 250 m high Mauvoisin arch dam, located in southern Switzerland, was investigated with respect to the maximum credible earthquake and a peak ground acceleration of 0.33 g. The results of an artificially generated spectrum-compatible earthquake with three stochastically independent components of the ground motion were compared with those of the natural earthquake of Friuli. Significant system parameters were calibrated with the measured behaviour and structure-foundation-fluid interaction was considered. Assuming massless foundation and a compressible reservoir, a linear dynamic analysis was carried out in the time domain. (5 refs.)

Abstract: Finite element formulations for fluid-structure interaction, assuming an inviscid fluid, can be classified into two major categories: displacement-based formulations and potential-based formulations. Although displacement-based formulations have been used widely, the methods suffer from the presence of spurious circulation modes and locking behavior. Potential-based formulations are inherently irrotational and do not have the difficulties of the displacement-based formulations. Nevertheless most of the applications of these methods are still limited to cases with relatively small motions. We introduce in this paper an arbitrary Lagrangian-Eulerian formulation using the velocity potential and the density as fluid variables. The formulation can be applied to problems in which the fluid undergoes very large boundary motions and can be used equally well for both compressible and incompressible fluids. (16 refs.)

Abstract: In this paper the finite element method is used to explore the mechanics of micro-indentation of polymer-based materials. In this study, we seek to model indentation as a means of eventually modelling the pin-on-disc wear test as it is used to cause fatique wear. The material selected is a possible replacement for metallic dental restorative materials. This elastic/plastic study is carried out to investigate the stress behavior and possible failure of the materialwhich may lead to its wear. Two commercial packages, ADINA & ANSYS, were used to model the problem. The primary objective of this paper is to study the distribution of the stresses and the corresponding strain behavior around the contact area in order to edify crack phenomena. The large-deformation analysis is repeated for various indentor penetration depths. The resulting stress analysis is then compared with the Hertz stress. Among the quantities readily computed are the indentation loads, contact areas and the surface profiles under load. Some of the results are then compared to the experimental data. (23 refs.)

Abstract: The ADINA finite element program was employed to investigate the state of stress in Cofired Multilayer Ceramic packages due to Thermal Coefficient of Expansion (TCE) mismatch between the ceramic and tungsten vias. Single, staggered and stacked vias were modeled near the ceramic surface, cavity edge and ceramic edge to produce general design recommendations on placement of vias. The tangential, first and second principle stresses were generated and used in a crack propagation study to determine effects on hermeticity. Theoretical results were experimentally verified by examining several cofired multilayer ceramic packages that failed due to severe thermal shock. (4 refs.)

Investigation of dynamic pulse buckling of thick rings

Pegg, N.G. (Defence Research Establishment Atlantic) Source: Journal of Applied Mechanics, Transactions ASME, v 59, n 3, Sep, 1992, p 615-621

ISSN: 0021-8936 CODEN: JAMCAV

Abstract: The occurrence of dynamic buckling of thick rings responding to an impulse load is investigated by analytical and numerical solutions to the equation of motion and by nonlinear finite element analyses. An extension to the linearized analytical solution is made using a finite difference scheme which incorporates a nonlinear moment-curvature relationship to model the effects of elastoplastic behavior and strain-rate reversal on the buckle formation. The finite element solution to the problem is formulated with the nonlinear code, ADINA. A comparison of the results shows that the numerical solutions (and, in particular, the ADINA solution) predict a significant reduction in the amplitude of buckling response and an increase in the predominant wavelength of response with time, in comparison to the linear analytical solution. A limited comparison to published experimental results of dynamic pulse buckling of thick rings is also given. (11 refs.)

Abstract: The crack tip strain gauge method in the compliance technique was used to determine the opening load of notched crack of axle steel, and the nonlinear finite element ADINA program, to which the cyclic stress-strain curve of axle steel was applied, was used to analyze the stress-strain field ahead of the crack tip and the opening load of notched crack. The results of both the compliance technique and the numerical method were in good agreement. In this paper, the concept of the sensitive point is proposed and the key to the determination of the crack opening load in the experiment is to place a strain gauge at sensitive point. It is certified by both experimental an numerical methods that the sensitive point has the best linear relationship character and the value of strain is much greater. (5 refs.)

Abstract: This paper presents analysis and experimental research on an autofrettaged pressure vessel with a cone and cylinder connection. Non-linear loading stresses and strains and the unloading residual stresses and strains are considered. The residual stress and strain fields are obtained by the non-linear axisymmetric boundary element method (BEM). The results of the BEM are verified by means of the finite element method (FEM) program ADINA and compared with autofrettaged high pressure experiments. It is concluded that the calculated residual strains are in reasonable agreement with those determined experimentally. (12 refs.)

Prying and shear in end-plate connection design

Abstract: Seven large, extended end-plate connections with eight tension bolts were fabricated and tested to failure at the Fritz Engineering Laboratory. Lehigh University. At least one connection failed by bolt fracture, weld fracture, or plate shear fracture. Experimental results led to concerns for bolt prying forces and end-plate shear forces. Finite element analysis models, using shell elements for the end plate and beam flanges and plane-stress elements for the beam web, were developed for the connections. Elastic and inelastic finite element solutions were obtained by using the ADINA program to provide predictions of the magnitude of shear force in the plate projection and the increases in bolt force due to prying action. The analytically predicted bolt forces were compared with the experimentally measured forces and reasonable agreement was found. Simple design rules, which complement the current design procedures for unstiffened end-plate connections, are presented. (19 refs.)

Conference: Proceedings of the 8th ADINA Conference, Jul 17-19 1991, Cambridge, MA, USA

Abstract: Existing methods for the analysis of contact problems deal with the inequality constraints arising from contact conditions by means of an implicit iteration on all constraints. This paper presents a formulation for contact problems with friction for large deformations where all inequality constraints are enforced explicitly. A robust solution technique for the resulting system of nonlinear equations can then be used. This approach admits the use of line search procedures to enlarge the region of convergence.
