A Mesoscale Model for Interface-Mediated Plasticity: Investigation of Ductile and Brittle Fracture
Jinxin Yu, Alfonso H. W. Ngan, David J. Srolovitzb +1
The presence of interfaces and grain boundaries significantly impacts the mechanical properties of materials, particularly when dealing with micro- or nano-scale samples. Distinct…
Application of Rigorous Interface Boundary Conditions in Mesoscale Plasticity Simulations
Jinxin Yu, Alfonso H. W. Ngan, David J. Srolovitz +1
The interactions between dislocations and interface/grain boundaries, including dislocation absorption, transmission, and reflection, have garnered significant attention from the r…
A threshold dislocation dynamics method
Xiaoxue Qin, Alfonso H. W. Ngan, Yang Xiang
The Merriman-Bence-Osher threshold dynamics method is an efficient algorithm to simulate the motion by mean curvature. It has the advantages of being easy to implement and with hig…
