Microplasticity and yielding in crystals with heterogeneous dislocation distribution
Xu Zhang, Jian Xiong, Haidong Fan +1
In this study, we use discrete dislocation dynamics (DDD) simulation to investigate the effect of heterogeneous dislocation density on the transition between quasi-elastic deformat…
Cyclic-loading microstructure-property relations from a mesoscale perspective: An example of single crystal Nickel-based superalloys
Ronghai Wu, Michael Zaiser
Past models of stress-strain response under cyclic loading mainly rely on macroscopic equations which consider microstructure evolution indirectly or simply discard microstructure…
Properties of dislocation lines in crystals with strong atomic-scale disorder
Jianhui Zhai, Michael Zaiser
We use a discrete dislocation dynamics (DDD) approach to study the motion of a dislocation under strong stochastic forces that may cause bending and roughening of the dislocation l…
Cell structure formation in a two-dimensional density-based dislocation dynamics model
Ronghai Wu, Michael Zaiser
Cellular patterns formed by self-organization of dislocations are a most conspicuous feature of dislocation microstructure evolution during plastic deformation. To elucidate the ph…
