FORMULATION AND IMPLEMENTATION OF CONDITIONS FOR FRICTIONAL CONTACT

KENNETH RUNESSON, MAREK KLISINSKI, RAGNAR LARSSON

Finite element implementations of the classical (stick‐slip) and a regularized (elastic‐slip) friction laws are compared for a class of non‐linear slip criteria. The fully…

STRESS RESULTANT FINITE ELEMENT ANALYSIS OF REINFORCED CONCRETE PLATES

ADNAN IBRAHIMBEGOVIĆ, FRANÇOIS FREY

An efficient implementation of a constitutive model for reinforced concrete plates is discussed in this work. The constitutive model is set directly in terms of stress resultants…

NUMERICAL SIMULATION OF CONTINUOUS CHIP FORMATION DURING NON‐STEADY ORTHOGONAL CUTTING

G.S. SEKHON, J.L. CHENOT

A finite element model for numerical simulation of non‐steady but continuous chip formation under orthogonal cutting conditions is described. The problem is treated as coupled…

RIGID‐PLASTIC IMPLICIT SCHEME FOR NON‐ AND THREE‐DIMENSIONAL ANALYSIS OF METAL FORMING BY FINITE ELEMENT METHOD

G. DE SAXCE, Z.Q. FENG, G. TOUZOT

This paper is devoted to the analysis of metal forming with assumption of rigid‐plastic behaviour with strain hardening. As opposed to the classical rate problem formulation based…

RANK ANALYSIS OF RECTANGULAR MATRIX AS AN ELEMENT OF CONTINUATION METHOD

MACIEJ KOWALCZYK

This paper is concerned with rank analysis of rectangular matrix of a homogeneous set of incremental equations regarded as an element of continuation method. The rank analysis is…

DAMAGE SIMULATION IN HETEROGENEOUS MATERIALS FROM GEODESIC PROPAGATIONS

D. JEULIN

We propose a simplified method to simulate damage evolution in heterogeneous media from geodesic propagation calculations. The method introduced for the case of porous media…
