CrystalPlasticity

CP UMAT and CZM UEL for Abaqus

The most updated version of single crystal solver

Inputs (PROPS)

PROPS(1): phi1 - 1st Bunge angle

PROPS(2): PHI - 2nd Bunge angle

PROPS(3): phi2 - 3rd Bunge angle

PROPS(4): grain-ID

PROPS(5): material-ID

PROPS(6): "0" for using usermaterials.f / "1" for manual entry to PROPS

The user entries are given in userinputs.f / useroutputs.f / usermaterial.f files
