Nonlinear analysis of reinforced concrete thin-walled beams and frames Sekulovic, Miodrag (Univ of Belgrade); Pujevic, Branislav Source: Computers and Structures, v 32, n 3-4, 1989, p 861-870 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: A method of analysis for three-dimensional reinforced concrete thin-walled beams and frames based upon the finite element displacement formulation is presented. A stiffness matrix for the analysis of thin-walled beams with an arbitrary open cross-section consisting of longitudinal filaments to represent the concrete and reinforcing steel is derived. The description of the element is based on the assumptions introduced by V.Z. Vlasov, and a method of describing the warping of a cross-section, which is valid for both straight and curved members with either open or closed cross-sections. An updated Lagrangian formulation is used to take into account the material nonlinearities and the effects of changing structural geometry. (21 refs.)

Concrete cracking analysis for the proposed arch raise of Roosevelt Dam Mays, John R. (Univ of Colorado at Denver); Dollar, David A.; Roehm, Louis H. Source: Computers and Structures, v 32, n 3-4, 1989, p 679-689 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: A proposed modification of an arch dam was subjected to parallel linear and nonlinear static analysis using ADINA 84. The load path selected for comparison produced high tensile stresses in the linear model and therefore significant cracking in ADINA's concrete model. The analysis clearly shows the ability of the arch dam to redistribute the loads after extensive cracking has occurred. (3 refs.)

Finite element analysis of temperatures and stresses in a single-pass butt-welded pipe - influence of mesh density and material modelling Karlsson, C.T. (Chalmers Univ of Technology) Source: Engineering Computations (Swansea, Wales), v 6, n 2, Jun, 1989, p 133-141 ISSN: 0264-4401 CODEN: ENCOEN Abstract: Single-pass girth butt welding of a carbon-manganese pipe is studied numerically using the finite element codes ADINAT/ADINA. This model is used to investigate the influence on the residual stress state of pipe geometry, mesh density and material modelling. Results are compared with previous results from two different FE analyses and an experimental investigation. One of the FE analyses was fully three dimensional and the other employed shell elements. The calculated residual stresses were found to differ significantly only when different material models were employed. The thermal strain seemed to be the material parameter with the largest influence on the residual stress state. Especially the changes in thermal strain during phase transformations seemed to have a great influence. Almost the same residual stresses were obtained for two pipes with different pipe geometries and weld parameters. (23 refs.)

Techniques using the ADINA-T thermal analysis program which have been found to provide suitable thermal modeling of direct chip attach systems are discussed. Correlation between model and experimental data is provided, and guidance on which direct mount systems can be adequately modeled is described.

Specifically, the commercially available codes COPES/ADS and ADINA are employed for numerical optimization and finite element analysis, respectively; and software packages like MOVIE.BYU, PLOT10 and SUPERTAB are used for pre- and post-processing purposes. The finite-difference and semi-analytical (or implicit differentiation) approaches of design sensitivity analysis were explored with the ADINA code for static as well as dynamic problems; and a comparison of the two approaches is made in terms of computational efficiency, solution accuracy and the ease of software implementation. A broad range of element types (truss, beam, plate and 2D/3D continuum) are considered. Additional aspects of the subject are discussed. (21 refs.)

Automatic load incrementation for rubber-like bodies in contact Haggblad, B. (Asea Brown Boveri, Corp Research); Nordgren, G. Source: Computers and Structures, v 32, n 3-4, 1989, p 899-909 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 authors propose and study an algorithm for automatic load incrementation, suitable for general path-dependent problems with nonproportional loading and frictional contact phenomena. The load steps are chosen adaptively on the basis of the iteration history and the occurrence of special events, such as contact (material overlap). Automatic restart is made at the indication of the beginning of divergence or overlap. At overlap restart is made from the latest converged solution with a step chosen to reach a configuration immediately before contact, from which the analysis then proceeds with a strongly reduced step. The applicability of the algorithm is demonstrated on typical problems involving highly nonlinear rubber structures. (15 refs.)

On automatic mesh construction and mesh refinement in finite element analysis Chae, Soo-Won (Korea Inst of Machiney and Metals); Bathe, Klaus-Jurgen Source: Computers and Structures, v 32, n 3-4, 1989, p 911-936 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: A valuable approach for the automatic generation of effective finite element meshes is presented. The approach comprises, firstly, an initial mesh construction and, secondly, an h-version of adaptive refinement based on an error analysis. For the initial mesh construction, a robust triangulation scheme for 2D analysis and tetrahedronization scheme for 3D analysis are used, in which the elements are generated from the outside boundaries. For the adaptive refinement process, an error indicator is used with a relaxation factor to obtain efficient solutions. The initial mesh construction schemes have been implemented for 2D and 3D analyses whereas the self-adaptive mesh improvement procedure has only been implemented for 2D analysis. Example solutions are given to demonstrate the solution procedures. (20 refs.)

Application of local damage models to the numerical analysis of ductile rupture Sun, D.-Z. (Fraunhofer-Inst fuer Werkstoffmechanik); Siegele, D.; Voss, B.; Schmitt, W. Source: Fatigue and Fracture of Engineering Materials & Structures, v 12, n 3, 1989, p 201-212 ISSN: 8756-758X CODEN: FFESEY Abstract: Two damage models were implemented into the finite element program ADINA to study the correlation between microscopical damage and macroscopical material failure. In the first model, based on the Gurson yield function the nucleation, growth and the coalescence of voids were incorporated into the constitutive relations. In the second model the void growth was determined according to the Rice and Tracey model using the von Mises yield function, and material failure was simulated by eliminating the elements where the critical void growth ratio was exceeded. The numerical results for the local and global behaviour of the specimens were compared with experiments. The generality of the damage parameters was checked by investigating several specimen geometries. Both damage models deliver qualitatively consistent results with regard to the influence of the stress triaxiality on the void growth and on the beginning of the material failure. However, the Gurson model gives a more accurate numerical simulation because the damage development and the stress drop continue after the onset of void coalescence while the critical void growth model causes less convergence problems in the simulation of large crack extension. The J<sub]R</sub]-curve was estimated on the basis of both models. (15 refs.)

Finite element analysis of a rubber block in frictional contact Tabaddor, Farhad (Uniroyal Goodrich Tire Co) Source: Computers and Structures, v 32, n 3-4, 1989, p 549-562 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: In this study, the problem of a rectangular block, fixed over a face and in contact with a frictional flat surface on the opposite face, is considered. The rubber is modeled as the Mooney-Rivlin type of material. The effect of bulk modulus on the stiffness of the block is first investigated. The normal and the tangential forces are calculated for a wide range of coefficients of friction and the stick-slip phenomenon is predicted as a function of coefficient of friction. The loading conditions considered are compression of the block with normal force and the loading of the block with both normal and tangential displacements. The qualitative wear resistance features of the block are explored by the work density of the frictional contact forces in the loading process. (3 refs.)
