Discrete Dislocation Dynamics Modeling of Nanotwinned Materials: Orientation Effects in a Multilayer Twinned Structure of Copper
DeAn Wei, Michael Zaiser, Jing Tang +1
The impact of twin boundaries (TBs) on the microstructure evolution and plastic deformation mechanisms of face-centered cubic (FCC) metals has been extensively studied since the di…
Constitutive modeling of the tension-compression behavior of gradient structured materials
Jianfeng Zhao, Xiaochong Lu, Jinling Liu +4
Gradient structured (GS) metals processed by severe plastic deformation techniques can be designed to achieve simultaneously high strength and high ductility. Significant kinematic…
Grain boundary effect on nanoindentation: A multiscale discrete dislocation dynamics model
Songjiang Lu, Bo Zhang, Xiangyu Li +4
Nanoindentation is a convenient method to investigate the mechanical properties of materials on small scales by utilizing low loads and small indentation depths. However, the effec…
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…
