Molecular Dynamic Simulation of the Nano-Scale Void Defect of bcc Iron under Shock Loading

Abstract:

We carried out an atomic-scale study of the behavior of nanoscale void defect in shock loading condition by the means of non-equilibrium molecular dynamic simulation. Atom trajectory and local temperature were investigated in different stages in the non-equilibrium process in the conditions with specific shock speed. The results show that the local temperature is significantly affected by the nanoscale void defect of bcc iron and a hot spot is formed in the initiation stage of the shock loading compression and consequently the hot spot induces the melting of the sample.
