A linear model of ductile plastic damage
Description
A three-dimensional model of isotropic ductile plastic damage based on a continuum damage variable on the effective stress concept and on thermodynamics is derived. As shown by experiments on several metals and alloys, the model, integrated in the case of proportional loading, is linear with respect to the accumulated plastic strain and shows a large influence of stress triaxiality
Abstract (French)
On etablit un modele tridimensionnel d'endommagement plastique ductile isotrope fonde sur la notion de variable continue d'endommagement, sur le concept de contrainte effective et sur la thermodynamique. Identifie sur plusieurs metaux et alliages, le modele, integre dans le cas du chargement radial, est lineaire par rapport a la deformation plastique cumulee et montre une grande influence de la triaxialite des contraintesAdditional details
