Influence de l'anisotropie initiale et induite sur l'instabilité plastique en emboutissage

Abstract : The intented result of this thesis is to elaborate a model of the influence of the initial and the induced anisotropy onto the development of plastic instabilities during the deep-drawing process. The thesis is divided into three parts : the first part is a summary of biography concerning models of the influence of the plastic instability using structural criteria like localized or diffused necking. The second part is deduced to initial anisotropical hardening law. The solution procedure can be divided into three steps : linearized analysis of the plastic instability; the model of Marciniak-Kuczinski combined with the rotational effects; the application to strongly anisotropic materials (Ti-Zr). The third part considers the induced anisotropy simulated by a kinematic hardening model which also considers the rotational effect
