Strain-Gradient Crystal Plasticity Finite Element Modeling of Slip Band Formation in α-Zirconium
Two methods for the determination of geometrically necessary dislocation (GND) densities are implemented in a lower-order strain-gradient crystal plasticity finite element model. The equations are implemented in user material (UMAT) subroutines. Method I has a direct and unique solution for the dens...
