Rôle de l'endommagement sur la durée de vie en fatigue des matériaux composites stratifiés : application au domaine éolien

Abstract : The purpose of this thesis is to propose and identify a model of mechanical fatigue behavior written for the lamina level. The model would be able to predict damage evolution but also residual strength. Studied materials are bi or tri axial glass fibre reinforced plastics fabrics. This work excluded joints areas where out of plane stresses generate strong coupling between intra and inter laminar damage. The main goals of the thesis are: - Identify on the material of the study damage mechanisms and their coupling in quasi-static and fatigue - Characterize and model residual stiffness caused by damage mechanisms - Characterize and model fatigue damage - Characterize and model residual strength caused by damage mechanisms - Implement and test the proposed model (or the one chosen in the literature and changed if necessary) in a computer FE code
