摘要

In this paper, structural changes of aluminum crystal by the shock phenomena induced by irradiating the fourth harmonics of Nd:YAG laser were analyzed applying the modified molecular dynamics (MD). In the modified MD method, which has been developed previously by Ohmura and Fukumoto, the MD calculation for metal is carried out compensating the heat conduction by free electrons at each time step. Main conclusions are summarized as follows: (1) Shock wave is generated in the material due to laser irradiation and then travels to the interior. Its propagation velocity is equal to the velocity of longitudinal wave of the material. (2) Dislocations are generated at solid-liquid interface and in solid phase by the shock wave. They move in the direction of depth at first with the shock wave and then move at the velocity that does not exceed the propagation velocity of transverse wave of the material. (3) Strain energy of the shock wave is consumed to generate dislocations and drive them, and decreases gradually. Therefore, no dislocation is generated by too small strain energy. (4) Stress state of the vicinity of an isolated dislocation that is calculated by the modified MD gave good agreement with the results of the continuum theory.
