Study on The Calculation of The Stored Energy due to Defects at High-Strain-Rate Deformation Using Molecular Dynamics

분자동역학을 이용한 고변형률하에서 결함으로 인한 저장에너지 계산에 관한 연구

This paper addresses a theoretical study to calculate the amount of the stored energy due to vacancies during high-strain-rate deformation. The study concerns the role of excess vacancies, which can play an important role to increase the amount of stored energy. Molecular dynamics simulation using a 3D model is carried out and the result clearly shows that the excess vacancies are credited to generation of the stored energy.
