Abstract

This paper presents the simulation of high temperature tensile tests using two rheological models that couple plastic and viscolpastic theories to damage equations. A Finite Element Method is used to analyze the coupled effects between non-linear and damage behaviour. Comparison of predicted values with experimental data is performed. 1 Introduction The coupling effects arising at high temperature between non-linear (plastic and creep) and damage behaviours in a loaded structure are an important aspect of its structural integrity analysis. For this purpose, the French Atomic Energy Commission (CEA - FRANCE) has implemented, in its Structural Analysis Finite Element computer code CASTEM 2000, "Plastic/Dama
