【摘要】 对舰船板架在接触爆炸载荷作用下的变形问题进行了研究。基于变分原理得到四边固支的板架残余变形的近似计算公式,根据破坏准则给出了估算破口半径的近似方法,并与经验公式进行了比较,结果基本上是合理的,可应用于舰船结构在爆炸冲击波作用下的毁伤或防护方面的工程预测,从而为舰船的安全防护设计提供理论依据。更多还原

【Abstract】 Studied plastic deformation of naval panels subjected to contacted explosion loading.A formula is deduced for calculation the survivals deformation of four sides clipped panels based on variational principle.A approximately way is educed to compute the crevasse radius based on the given destroy rule.The result is reasonable compared with experiential value.The method can be applied to the engineering prediction of the damage or safety of the naval panels under explosive blast wave and can provide theory reference for safety design.更多还原
