在鱼雷攻击作用下，舰体结构会产生破口。将船体板架结构简化为交叉梁系结构，由交叉梁系结构的拉伸塑性应变满足断裂衡准时的塑性区范围来预测船体板架在接触爆炸载荷作用下破口的大小。将计算得到的结果与朱锡等加筋板架的试验数据进行对比，吻合良好。这表明力学模型选取合理，具有一定的工程实用性。

Under the attack of torpedo, crevasse will be produced. An estimation of crevasse size of hull grillage under contact explosion is put forward, in which hull grillage structure is simplified to a cross beam system, and tensile plastic strain of the system in plastic zone meets the fracture criterion. Theoretical estimation is compared with the stiffened plate’s tests which are performed by Zhu Xi. It is shown that the selection of mechanical model is reasonable, and the estimation method ensures engineering practicability.
