유한요소법을 이용한 다결정 나노박막의 기계적 거동 해석

In this study, molecular dynamics simulation is performed to investigate the mechanical behavior of bi-crystalline nanofilms under uniaxial tensile or simple shear loading. Three bi-crystalline nanofilms with {100} surfaces having different crystal orientation are considered as the simulation models. It is interestingly shown that the maximum stress before starting plastic deformation is nearly same regardless grain orientation.
