Abstract
This paper presents a constitutive law based on Taylor's model implemented in our non-linear finite
element code LAGAMINE. The yield locus is only locally 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.
