摘要
根据能量原理,采用层合板理论和薄板大变形理论,对四边固支的矩形正交铺层的纤维增强复合材料薄板在爆炸冲击波作用下的弹性大变形进行理论分析,得到了层合板的最大挠度计算公式。有限元数值模拟计算表明,理论计算结果与有限元数值模拟的结果吻合较好,因此该方法可用来对复合材料板在弹性范围内的最大挠度进行预测,同时认为根据薄板的最大挠度,可以计算板的应力(应变)分布和复合材料板失效时的爆炸载荷。
This paper dealt with the maximum deflection of the clamped rectangular orthogonal composite laminate plate subjected to shock wave according to the principle of energy,the theories of laminate and the thin plate large deformation.The function of the maximum deflection composite la-minate plate was obtained on the basis of analysis.The maximum deflection of numerical simulation is consistent with the theoretical calculating data and the maximum deflection of composite laminate plate can be predicted among elastic range.The stress（stain） distribution of plate and the failure loads of plate subjected to shock wave can be calculated according to the maximum deflection of composite laminate plate
