利用不同材料界面的连接条件，将问题中所有各量用单一未知函数表达，用积分变换方法将受突加载荷作用问题化为对偶积分方程，并用Ｃｏｐｓｏｎ方法［１］求得了不同粘弹性材料组成的层状结构中受突加载荷的裂纹动力学问题的一般解。裂纹表面受任意动载荷作用问题都可使用本方法求解。
Using the connection conditions of different material interfaces, all the quantities in the problem are expressed by a single unknown function, and the problem of sudden load loading is transformed into the dual integral equation by the integral transformation method. The Copson method [1] The general solution to the cracked dynamics problem in layered structures. Crack surface by any dynamic load problem can be solved using this method.
