Moving Screw Dislocation Near Interfacial Rigid Lines in Two Dissimilar Anisotropic Media

  • 摘要: 研究了各向异性双材料中匀速运动螺型位错与界面刚性线的干涉问题.运用Riemann-Schwarz解析延拓技术与复势函数奇性主部分析方法,获得了该问题的一般弹性解答,求出了界面含一条和两条刚性线情况下的封闭形式解,并给出了刚性线尖端的应力强度因子和作用于运动位错上的像力的显式表达式.结果表明,位错速度增大可以削弱位错对应力强度因子的反屏蔽效应;位错速度越大,位错平衡点越靠近刚性线.退化结果与已有的解答完全吻合.
