| 摘 要： | 试验研究了潜艇艇体用钢在爆炸冲击载荷作用下的动态极限应变。利用体积等效原理,得到了潜艇的两种典型结构在双向应变假设和单向应变假设下的动态开裂应变。试验结果可为潜艇艇体结构在爆炸冲击载荷作用下破损进水的数值仿真提供开裂判据。

| Abstract: | Experimental investigation were carried out on dynamic failure strain of submarine steel under shock loading. On the assumption of bi-directional and uni-lateral strain, dynamic failure strain of two submarine representative structures were measured according to the volume equivalent principle. Crack criterion was also discussed. Results could be used as the crack criterion for computer simulate on failure of submarine shell subjected to explosive loading. |

| Keywords: | mechanics of explosion crack criterion dynamic failure strain submarine shock |
