Abstract The microstructure of crystal defects, e.g., dislocation patterns, are not arbitrary, and it is possible that some of them
may be related to the microstructure of crystals itself, i.e., the lattice structure. We call those dislocation patterns or
substructures that are related to the corresponding crystal microstructure as the Geometrically Compatible Dislocation Patterns (GCDP). Based on this notion, we have developed a Multiscale Crystal Defect Dynamics (MCDD) to
model crystal plasticity without or with minimum empiricism. In this work, we employ the multiscale dislocation
pattern dynamics, i.e., MCDD, to simulate crystal plasticity in body-centered cubic (BCC) single crystals, mainly
α-phase… More >
