| 摘 要： | 大型水面舰船的防护舱壁需要设计成工作在薄膜应力状态下.本文利用能量法推导了在爆炸载荷作用下防护舱壁塑性薄膜大变形的计算公式,给出了一个工程简化计算方法.并对防护舱壁的设计要求进行了讨论,与国外发表的有关试验结果进行了计算比较,结果表明两种方法都具有一定的应用价值.

| Abstract: | The protective bulkhead of a large surface warship needs to be designed working in the membrane stress mode.In this paper,a formula is rived for calculating the plastic deformation of the protective bulkhead subjected to blast loading by the energy method.A simple formula for engineering use is given.The design requirement of the protective bulkhead is discussed.The calculation is compared with experimental result in published reference.It is shown that two formulas are of great applicable value. |
