Abstract:

Rate-dependent crystal plasticity constitutive model has been employed into finite element software ABAQUS to simulate surface asperity flattening in uniaxial planar compression. Measured textures and surface roughness are introduced into the 3D surface roughness model. The calculated results show a good agreement with the experimental results. With an increase of reduction, the surface asperity flattening tends to increase, and Goss texture {011} <100> and brass component {110} <112> become stronger, whilst the cubic texture {001} <100> becomes weaker. If the reduction reaches 40%, Schmid in-grain shear band appears and the strain localisation starts. The evolution of surface feature (roughness) shows the obvious sensitivity on the orientation {111} of near-top surface. © Springer Science+Business Media, LLC 2012.
