| 摘 要： | 本文提出了一种分析考虑裂纹面摩擦影响的可接触型裂纹动力反应的时域显式计算方法，这一方法不但可以较好描述裂纹面之间碰撞过程，也能反映当裂纹面发生接触－滑移时，裂纹面间动、静摩擦力的影响．文中给出了使用这一方法的基本步骤，计算了无限大裂纹的动接触问题和直线型裂纹对入射Ｐ波的散射问题，初步验证了本文提出的方法．

| Abstract: | This paper proposes an explicit met hod for analyzing the dynalnical re-sponse of the contactable cracks with friction in the crack surface,The method can be usednot only to simulate the process of impaict of the crack surfaces,but also to consider theeffects of static and kinematic frictional resistance when contact-slip of crack surface occurs. Dynamical contact of an infinite crack and scattering of P wave by a contactable crack inhalf-space are calculated.The results indicate that the method in the paper is accurateenough. |
