Plasticité anisotrope couplée à un endommagement ductile isotrope : Application au gonflement hydraulique de tôles minces

Abstract : This work deals with the study of anisotropic elastoplastic constitutive equations fully coupled to the isotropic ductile damage in order to examine the effect of the anisotropic plastic flow on the “isotropic” damage evolution. An anisotropic quadratic yield criterion accounting for nonlinear isotropic and kinematic hardening is used. This fully coupled model is implemented into ABAQUS FEA Software. Both the theoretical and related numerical aspects are briefly discussed. Application is made to the failure prediction of a thin sheet metal subject to the hydrobulging test using an elliptic matrix. The experimental and numerical results are compared and discussed.
