Abstract

In this paper, the Low Cycle Fatigue (LCF) damage evolution of weld Heat Affected Zone (HAZ) is studied by use of Continuum Damage Mechanics. Based on a continuum damage variable, D, on the effective stress concept and on thermodynamics, a continuum damage model of isotropic LCF is derived, and is used to analyse the LCF damage evolution of thermally simulated HAZ. A comparison between model and the experimental results is presented and a good agreement is found.
