WebbGao, B., & Kakimoto, K. (2014). Dislocation-density-based modeling of the plastic behavior of 4H–SiC single crystals using the Alexander–Haasen model. Webb6 maj 2008 · Dislocation dynamics simulations have been used to study the stress-strain response of single-crystal micropillars containing initial dislocation networks generated via a relaxation procedure intended to approximate real thermal annealing processes. We find that, when such networks are loaded, they exhibit periods of plastic deformation, caused …
