To solve the problems of the interaction between the unilateral interface cracks and elastic wave, a new numerical method based on boundary element method (BEM) has been pro posed in the current paper.
借助边界元法设计了一种迭代修正方法来求解单侧界面裂纹模型与弹性波的相互作用问题，作为对算法的检验，用这种方法我们具体地分析了平面简谐弹性波对一个单侧界面裂纹的入射，给出了裂纹面的接触形态及应力场。
