摘    要:本文研究了两种不同正交异性材料界面半无限长裂纹,在冲击荷载下的动态弹塑性响应。通过积分变换,Wiener-Hopf方法和Cagniard-deHoop反演围通技术,求得一般解析解,获得了该裂纹的动应力强度因子;通过采用Dugdale模型,建立了裂纹尖端塑性区延伸速度与裂纹扩展速度的关系,以及动态COD与裂纹扩展速度的关系。

关 键 词:正交各向异性,界面裂纹,裂纹扩展冲击荷载

Abstract:In this paper, the elastic-plastic dynamic response at the tip of semi-infinitecrack in the interface between two dissimilar orthotropic materials subjected to impact isinvestigated. By means of the integral transform, Wiener-Hopf technique and Cagniard-deHoop's inverting path,the analytic solution of the question is acquired,and then the dynamicintensity factor of the crack is also obtained. By using Dugdale mode,tWo relations areobtained.One is the extending velocity of its plastic domain with the propagating velocityof the crack,and another is the dynamic COD with the propagating velocity of the crack.
Keywords:orthotropic materials  interface crack  crack propagating  impact
