Comparative investigation of sheet metal forming processes by the elastic‐plastic finite element method with emphasis on the effect of bending

D.Y. Yang, H.B. Shim, W.J. Chung

The effect of bending is investigated through the comparison of the membrane analysis and the shell analysis for stretching and deep drawing. An incremental formulation…

A one point integrated assumed strain 4‐node Mindlin plate element

H. Kebari

The 4‐node assumed strain elements are among the best elements available today but the bending moments at their full integration points oscillate severely. This paper presents a…

Displacement and stress convergence of our MITC plate bending elements

Klaus‐Jürgen Bathe, Miguel Luiz Bucalem, Franco Brezzi

We briefly summarize the theoretical formulations of our MITC plate bending elements and then present numerical convergence results. The elements are based on Reissner‐Mindlin…

A fully non‐linear axisymmetrical membrane element for rubber‐like materials

P. Wriggers, R.L. Taylor

An axisymmetrical membrane element for large deformations is developed which is based on Ogden's non‐linear elastic material law. Special attention is given to the linearization…

Design of an optimal grid for finite element methods in incompressible fluid flow problems

B. Ramaswamy, J.E. Akin

Finite element solutions of improved quality are obtained by optimizing the location of nodes of the finite element grid, while keeping the number of degrees of freedom fixed. The…

Structural analysis and optimization of a propfan‐blade by use of the finite element method

Rolf Lammering

Structural analysis of advanced propellers (propfans) is only possible by use of numerical methods because, due to the geometry and the loading, a geometrically non‐linear…

Numerical modelling and non‐linear analysis of the behaviour of maxillary partial denture

H.J. Böhm, F.G. Rammerstorfer, R. Schmid, A. Starlinger, R. Slavicek

The biomechanical problem of investigating the behaviour of a maxillary partial denture is treated by non‐linear finite element analyses. The finite element models developed allow…

Rigid contact modelled by CAD surface

Erik Hansson, Anders Klarbring

The present paper deals with the problem of large displacement frictionless contact between a rigid obstacle and an elastic body. In Klarbring a formulation of this problem which…

Automatic generation of shape functions for finite element analysis using REDUCE

Christine Barbier, Philip J. Clark, Peter Bettess, Jacqueline A. Bettess

The use of algebraic languages such as REDUCE makes possible the automatic generation, from fairly concise data, of the main families of two and three dimensional C0 continuous…
