104 延性材料の衝撃破壊エネルギ吸収特性に関する研究  [in Japanese] A study of absorption characteristic penetration energy for ductile material  [in Japanese]

In this paper, experimental formula of energy absorption prediction for crack initiation and penetration of conical projectile into ductile metal sheet are derived in order to apply to evaluate the crash worthiness of honeycomb structures. Moreover, the projectile penetration phenomena are simulated by implementing dynamic analysis using LS-DYNA, and the numerical results are compared with experimental ones.
