Modelling surface roughening with crystal plasticity

The development of surface topography during plastic straining is important in many aspects of a materials performance, including aspects of formability and fracture, as well as surface appearance. In this paper plastic deformation induced surface roughening is simulated using the finite element method, which is based on crystal plasticity and directly incorporates measured EBSD (grain orientations and their spatial distributions). The effects of initial texture and its spatial distribution on the development of roughness are discussed.
