摘要
建立含有离散位错的层状材料力学模型;采用应力场修正方法,使用Airy应力函数及Fourier变换获得层状复合材料中单个位错应力场的弹性解;最后使用应力场叠加方法分析了位错和界面的耦合效应.
The mechanical model for a set of dislocations in an elastic isotropic layer sandwiched between two adherends of different materials is presented. The superposition technique and the method of Airy function along with Fourier transform are used to obtain the elastic solution of a single dislocation in a three-layered material system. Finally by using superposition methods the combined interaction of dislocations and interfaces is analyzed .
