在爆炸冲击载荷作用下层板的应力分析

The Analysis of Stress of Layered Plate Subjected to Impact and Exploding

利用积分变换及层板的联结条件,给出了层板受冲击和爆炸载荷作用问题的解的一般表达式。层板各层材料不同,厚度也不同.文中利用围道积分技术进行了拉氏反演从而得到了物理空间的解,同时利用数值计算给出了不同材料常数对层板冲击响应的影响情况。它有助于我们对层板的应力分析。

A general solution for the problem of a layered plate subjected to impact or exploding load is presented,the formal solution is obtained by using integral transform and continuous condition among the layers.Each layer of the plate has different material and thickness.The Laplace inverse transformation was done by using contourintegral technique,so the solution of physic space is obtained.Meanwhile,by usingthe numerical calculating method the relations between the different material constantsand impact answers of layered plate were given.It is useful to use these results to ana-lyse stress of layered plate.
