The growth of voids from some seeds by using atom and macro scale analysis

Abstract

We study the growth of the void. where multiple seeds at the initial condition. A square unit cell with some atomic defects is constructed with nickel atoms and is subjected to the hydrostatic tensile load by using Molecular Dynamics. A same configured model with some small voids is simulated by using FEM. We observed the void growing and the void vanishing by the influence from the other voids. The behaviors of the voids initiation by the two methods. which are microscopic and macroscopic method. are compared to each other.
