박판 정 4각튜브의 동적 평균압괴하중

Assuming that the static loaded square tube and the dynamic loaded one have no diin their characteristics of the crush distance, the theoretical mean dynamic crush load was calculated with respect to the impact speed considering the strain rate sensitivity of the material. The ratio of dynamic to static mean crush load was predicted with previous results. The theoretical analysis was compared with the experimental results of aluminum square tubes axially loaded dynamically.
