Nov 13, 2009 · VPSC is a computer code written in FORTRAN 77 which simulates the plastic deformation of polycrystalline aggregates. VPSC stands for Visco Plastic Self Consistent and refers to the particular mechanical regime addressed (VP) and to the approach used (SC). VPSC was developed for application to low-symmetry materials (hexagonal,
