Showing papers in "Finite Elements in Analysis and Design in 1986"

TL;DR: An assessment is made of the potential of different global-local analysis strategies for predicting the nonlinear and postbuckling responses of structures and the key elements of each of these strategies are discussed.

TL;DR: An overview of the current capabilities of thirty-three computer programs that are used to solve heat transfer problems is given in this paper, which is based on a questionnaire sent to the developers of each program.

TL;DR: An example, showing how feedback information generated by p-extension can be used for controlling the quality of the finite element solution, is presented.

TL;DR: The relationship between finite element analysis and reliability is discussed in this article, where a quantitative measure for the reliability of finite element programs is presented in the form of a reliability profile which expresses the functional relationship between the results of the analysis, the difficulty of the application, and the proficiency of the user.

TL;DR: In this paper, the authors present an approach to the unification of geometric modeling and finite element modeling based on automated procedures, arguing that an automated finite element modelling approach is the only viable approach to carry out this unification.

TL;DR: In this paper, three-dimensional thick shell elements with 8, 16, and 18 nodes were formulated by using the hybrid/mixed method, and their behavior characteristics regarding sensitivity to locking, distortion effect (patch tests), mesh convergence and the accuracy of stress evaluation were analyzed.

TL;DR: An introductory insight into this newly emerging commercial capability for re-analysis with a minimum of additional data preparation and user interaction is given and focuses on displacement-based elements.

TL;DR: The results show the potential of parallel computers to provide significant increases in computation speed over sequential computers in such computation intensive problem areas as eigenvalue analysis and transient response.

TL;DR: The 1984 version of the ADINA system is briefly described in this article, and the philosopy behind the program development is given, and the elements, material models, numerical solution methods, pre-and post-processing capabilities and the documentation available on the programs are briefly summarized.

TL;DR: EAL (Engineering Analysis Language) is a high order command language for structural, fluid, and thermal finite element analysis and design that is equally suited for batch and interactive operation.

TL;DR: In this paper, a complete elastic-plastic plane-stress solution for strain hardening materials obeying a Von Mises yield condition and Prandtl-Reuss stress-strain relations is obtained using only constant strain elements.

TL;DR: In this article, a modified rigid body spring model (RBSM) is proposed for elasto-plastic analysis of the cantilever beam with the built-in edge taken as a contact problem.

TL;DR: Current capabilities in these areas are covered, their interaction is discussed, and some trends in capabilities for the personal computers are predicted.

TL;DR: In this paper, the authors present a structural model, an analysis procedure, and illustrative results for two-dimensional trusses with slots small compared with member lengths. But the analysis process implies stepwise linear behavior.

TL;DR: In this article, a general method of calculating the fields in the conductors of unknown boundary conditions upon their surface is presented, combining the Bubnov-Galerkin method in its numerical form with the separation of variables by means of the finite element method so that the analysis of skin effect in conductors placed in homogeneous, isotropic medium is possible.

TL;DR: In this article, an assessment of CAD/CAM and related areas including various aspects of Automated Manufacturing and Robotics is given, and some perspectives are given of developments and prospects in artificial intelligence.

TL;DR: The history and key concepts of the finite element method (FEM) are described, and issues related to its unification with the former are discussed.

TL;DR: The general capabilities and the particular hardware environment of an interactive color graphical postprocessor for three-dimensional numerical analysis are described and examples of various result parameters—scalar, vector, and tensor—from finite difference, finite element, and boundary element analyses are presented.

TL;DR: The CADS modular organization and its capabilities are examined in detail and several examples are used to illustrate its broad band of capabilities.

TL;DR: In this paper, a unified approach to solving combined/coupled electromagnetic and steady state heat conduction problems is described, illustrated by application to an illustrative slot embedded conductor problem in electrical machines carrying a.c.current.
