The prediction of damage development under hypothetical accidental loading constitutes a major stake to guarantee the safety of industrial installations: nuclear power-plants, pipelines, etc. It is then important to correctly predict crack initiation and propagation. The aim of this work is to develop and implement a reliable and efficient strategy to predict crack initiation and propagation over long distances using the Finite element Method (FEM) in the scope of local approach ro failure. The first part of the thesis consists in developing a mesh objective GTN damage model adapted for metals such as construction steels. To do so an implicit gradient nonlocal model with two internal length scales was developed and implemented in the Z-set ...
