Nonlinear analysis of fracture mechanics problems

Keim, Elisabeth (Siemens AG); Mueller, Gerhard Source: Computers and Structures, v 32, n 3-4, 1989, p 737-743

ISSN: 0045-7949 CODEN: CMSTCJ

Conference: Nonlinear Finite Element Analysis and ADINA - Proceedings of the 7th ADINA Conference, Aug 2-4 1989, Cambridge, MA, USA

Abstract: The requirements of a finite element program appropriate for fracture mechanics analyses are briefly summarized. The aim of these analyses and the fracture mechanics parameters are shown as well as the difficulties arising with the application. Some typical two- and three-dimensional elastic-plastic analyses of fracture toughness specimens and structures being loaded by mechanical or/and thermal loads are presented and the results are compared to experimental data and literature values. Special application cases for large deformations or creep processes are discussed. (15 refs.)

Numerical Investigations of the Influence of Implant Shape on Stress Distribution in the Jaw Bone

D. Siegele, U. Soltész

Int J O Ral Maxillofac Implants, 4:333-340, 1989

Abstract: The stress distribution generated in the surrounding jaw bone was calculated and compared for different types of dental implants (cylindrical, conical, stepped, screw-shaped, hollow cylindrical) by means of the finite-element method. Both a fixed bond and a pure contact without friction between implant and bone were considered as interface conditions. The results demonstrate that different implant shapes lead to significant variations in stress distributions in the bone. In particular, implant surfaces with very small radii of curvature (conical) or geometric discontinuities (stepped) imply distinctly higher stresses than smoother shapes (cylindrical, screw-shaped). Moreover, a fixed bond between implant and bone in the medullary region (as may be obtained with a bioactive coating) will be advantageous for the stress delivered to bone, since it produces a more uniform stress distribution than does a pure contact.

Application of a finite element code in the analysis of motorcycle road behaviour

De Molina, C. (Technical Univ Berlin) Source: Computers and Structures, v 31, n 5, 1989, p 789-794

ISSN: 0045-7949 CODEN: CMSTCJ

Abstract: A new nonlinear method for the simulation of the driving behaviour of single-track vehicles has been developed. It allows a more precise modelling of all the motorcycle parts than the usual multibody-system method does. Some tyre models as well as the gyroscopic, aerodynamic and road effects have also been implemented. A comparison with running tests shows the accuracy of the presented approach. (11 refs.)

Interactive preprocessors for SAP IV NASTRAN and ADINA In the teaching environment

Kaldjian, Moves J. (Univ of Michigan) Source: Computers and Structures, v 33, n 3, 1989, p 885-895

ISSN: 0045-7949 CODEN: CMSTCJ

Abstract: A preprocessor can be made to accommodate internally the input data variations peculiar to each finite element program. Learning to model on one finite element program may then be adequate to allow the engineer to prepare data for other finite element programs through a well planned preprocessor. Three such preprocessors, PREMSAP, PNASTRAN and PADINA, have been developed in Fortran for SAP IV, NASTRAN and ADINA respectively. Typical interactive conversations of these, and their output, are presented here for a 3D bracket, and may be compared. These preprocessors, coupled with a graphics package, proved very useful in training students in finite element analysis in class study, as well as with engineers and researchers in their work.

Abstract: A hybrid experimental numerical procedure is described for determining the dynamic fracture toughness JID of propagating cracks in ductile steels. The procedure is based on an experimental determination of the crack propagation history and a subsequent evaluation of these data by numerical techniques. Two-dimensional and three-dimensional dynamic finite element calculations are performed using an extended version of the ADINA code. The validity and the accuracy of the procedure is checked in the linear elastic regime by comparison with experimental data obtained by shadow optical techniques. The described methodology is applied for determining the crack-propagation fracture toughness JID of the pressure vessel and piping steel 20 MnMoNi 55. (10 refs.)

Convergence of finite element frequency predictions for a thin walled cylinder

Abstract: The ADINA finite element computer program has been used to calculate the natural frequencies of a thin walled cylinder with both ends clamped. The 16-node quadrilateral curved shell element was applied to three progressively refined computational meshes in order to numerically estimate rates of convergence and limit frequencies. Two orders of integration were employed: 3 x 3 x 2 and 4 x 4 x 2. For each mesh and order of integration the subspace iteration method was used to calculate the first 100 frequencies. The finite element frequencies were compared with those from a Rayleigh-Ritz solution to the Kirchhoff shell equations. Calculations confirmed that frequencies converge from above, in agreement with the use of a consistent mass matrix. Frequencies obtained with the lower 3 x 3 x 2 order of integration were closer to converging than those obtained with the higher 4 x 4 x 2 order of integration. Convergence was found to correlate with mode shape rather than frequency, with modes having fewer oscillations being closest to converging. (10 refs.)

Use of ADINA to model large deformation of the earth's lithosphere

Conference: Nonlinear Finite Element Analysis and ADINA - Proceedings of the 7th ADINA Conference, Aug 2-4 1989, Cambridge, MA, USA

Abstract: This paper develops a Lagrangian displacement-based approach to the large-scale deformation of the lithosphere, the earth's outermost rheological layer. The lithosphere is characterized by rapid vertical variation of mechanical properties and deformation mechanism. The latter is though to range from strongly temperature-dependent dislocation creep at a depth of about 100 km, to elasto-plasticity at the surface. The discussion summarizes the use of the Updated Lagrangian Henky technique, available in ADINA 5, to model finite strain in a rheologically complex continuum resembling the lithosphere. Non-linear finite element models of lithospheric deformation are compared to analytic results based on linearized equations. (42 refs.)

Combined ADINA-finite difference approach with substructuring for solving seismically induced nonlinear soil-structure interaction problems

Conference: Nonlinear Finite Element Analysis and ADINA - Proceedings of the 7th ADINA Conference, Aug 2-4 1989, Cambridge, MA, USA

Abstract: A combined finite difference-finite element with substructuring approach is proposed for solving seismically induced nonlinear soil-structure interaction problems. The substructuring is achieved by employing a super-degree-of-freedom, instead of the structure, combined with an explicit finite difference code, and the resulting interface conditions are then used as input for analyzing the structure alone with ADINA. The results demonstrate that the combined approach is efficient and economic, as compared to the pure finite element analysis. (21 refs.)

ISSN: 0045-7949 CODEN: CMSTCJ

Abstract: Using ADINA, the inelastic response of a simple cylindrical arch dam of constant thickness and vertical banks due to differential foundation and abutment movements is analysed. Small displacements and strains are assumed. The mass concrete is idealized as an elasto-plastic material, where the yield stress in each element of the discretized dam is obtained from the biaxial failure envelope of concrete. A vertical ground movement is assumed, beginning at the centre of the arch and increasing linearly towards the abutment. (9 refs.)

Conference: Nonlinear Finite Element Analysis and ADINA - Proceedings of the 7th ADINA Conference, Aug 2-4 1989, Cambridge, MA, USA

Abstract: In order to achieve the extremely high magnetic fields (8 to 10 Tesla) required for CERN's LHC (large hadron collider) project superconducting coils are used in the deflecting magnets. One possible technology is the use of the brittle material Nb3Sn, which must be kept at low temperatures (4.2 K). The cooling down process and the variation of the strong electromagnetic forces during operation require special care. These situations are simulated by a finite element model taking into account the frictional contact between the individual components of the magnet assembly. In addition to the stress and strain distribution in the magnet the knowledge of local relative motions generating frictional heat is important for the consideration of the stability of the superconducting material.

Abstract: This paper describes a portion of studies wherein various viscoplastic constitutive models, dynamic crack-propagation algorithms, and proposed nonlinear fracture criteria have been installed in the general purpose ADINA finite element computer program. The predictive capabilities of the nonlinear techniques are evaluated through analyses of crack-arrest tests of nonisothermal wide-plate specimens. Values of fracture parameters calculated by elastodynamic and viscoplastic-dynamic techniques are compared to assess the impact of including viscoplastic effects in the computational models. Mesh refinement studies are presented that examine whether the proposed fracture parameters converge to nonzero values in viscoplastic-dynamic analyses or whether they are controlled by element dimensions. Plans are reviewed for additional computational studies to assess the utility of viscoplastic analysis techniques in constructing a dynamic inelastic fracture mechanics model for ductile steels.

Conference: Nonlinear Finite Element Analysis and ADINA - Proceedings of the 7th ADINA Conference, Aug 2-4 1989, Cambridge, MA, USA

Abstract: Analytical studies with the ADINA computer code were performed to determine the Dynamic Load Amplification Factor (DLF) of metal beams and plates subjected to axial in-plane impact compression loading. The results were compared with experimental ones and those yielded by self developed finite differences programs. The influences of initial geometric imperfections, as well as duration of loading on the DLF were evaluated. As anticipated, the DLFs were usually higher than unity. However, in a few cases, in the presence of certain magnitudes of initial geometric imperfection and for loading durations close to the first natural period in bending, DLFs smaller than unity were observed.
