ROBUST FINITE ELEMENTS FOR 3D‐ANALYSIS OF RUBBER‐LIKE MATERIALS

P.A.J. VAN DEN BOGERT, R. DE BORST, G.T. LUITEN, J. ZEILMAKER

A marked characteristic of rubber‐like materials is the nearly incompressible behaviour. This type of behaviour is best modelled by mixed finite elements with separate…

AN ALGORITHM FOR GENERATION OF SHAPE FUNCTIONS IN SERENDIPITY ELEMENTS

G. ZAVARISE, R. VITALIANI, B. SCHREFLER

An algorithm to calculate shape function values at specific points is presented. It applies to three‐dimensional serendipity elements with variable node numbers per side and, as a…

THREE‐DIMENSIONAL NON‐LINEAR ANALYSIS OF REINFORCED CONCRETE BEAMS

ZHEFENG SUN, DENYS BREYSSE

Simplified methods are often employed for the analysis of reinforced concrete beams (R‐C beams). A three‐dimensional problem (3D) is often transformed into a two‐dimensional…

DYNAMIC STABILITY ANALYSIS OF A COMPOSITE MATERIAL CONNECTING ROD BY THE FINITE ELEMENT METHOD

LIEN‐WEN CHEN, DER‐MING KU

The Euler beam theory is used to study the dynamic stability of a composite material slider‐crank mechanism with an elastic connecting rod. The Ritz finite element procedure is…

ERROR ESTIMATION AND MESH OPTIMIZATION FOR CLASSICAL FINITE ELEMENTS

P. LADEVÈZE, J.‐P. PELLE, PH. ROUGEOT

We present several applications for 2D or axisymmetric elasticity problems of a method to control the quality of a finite element computation, and to optimize the choice of…

OBJECT ORIENTED PROGRAMMING IN SCIENTIFIC COMPUTATIONS: THE BEGINNING OF A NEW ERA

JOSÉ SERGIO RODRIGUES ALVES FILHO, PHILIPPE REMY BERNARD DEVLOO

Undoubtedly, Fortran dominates the field of scientific computing from commercial packages to university programs. Although Pascal and C have managed to seduce some programmers…
