Implementation of a texture based interpolated yield locus in a FEM code

Abstract

peer reviewedThis paper presents a constitutive law based on Taylor's model implemented in our non linear finite element code LAGAMINE. The yield locus is only described and a particular interpolation method has been developed. This local yield locus model uses a discrete representation of the material's texture. The interpolation method is presented and a deep-drawing application is simulated in order to show up the influence of the texture evolution during forming processes
