Direct micro-to-macro modelling of the cold rolling of pearlitic steel

Abstract

A crystal plasticity model is adapted in order to predict strength, internal stresses and texture development in pearlite. The model is used as the user-defined material law in macroscopic finite element simulation of rolling. It is shown that the material response depends strongly on the reorientation of cementite lamellae. The model produces good estimates of the lattice strains measured by neutron diffraction as well as the uniaxial tensile curve.
