摘要
利用坐标轴不平行于弹性主方向的应力、应变变换公式,并结合复合材料断裂复变方法,对正交异性双材料非弹性主方向半无限界面裂纹问题进行了研究,得到了用弹性主方向坐标系工程参数表示界面裂纹尖端的应力场、位移场。并给出双材料参数对半无限界面裂纹尖端应力场的影响规律。
By the help of the transformation formulas of stress and strain of non-parallel axis principal directions of elasticity,the semi-interfacial crack problem of double dissimilar orthotropic composite material in non-principal directions of elasticity was studied.The theoretical formula of the stress field and displacement field near interface crack tip were derived.The influences of bi-material parameters on the stress field are investigated.
