摘要
研究了周期平面内含任意裂纹的一维六方准晶的弹性半平面第一基本问题.首先借助保角变换将半平面第一基本问题转化为单位圆内带任意裂纹的第一基本问题;再利用复变函数方法将求有界域内的弹性平衡问题转化为奇异积分方程的求解,并证明方程是唯一可解的.该问题的求解为研究工程断裂问题提供了理论方法.
The first fundamental problem of elastic half plane of one-dimensional hexagonal quasicrystals with arbitrary cracks in the periodic plane is studied.First,conformal transformation is used to transform the first fundamental problem of a half-plane into the first fundamental problem with arbitrary cracks in the unit circle.Then,complex function method is used to transform elastic equilibrium problem in the bounded domain into the singular integral equation.Furthermore,the unique solvability of the equation is proved.It is provided a theoretical method for studying the engineering fracture problem.
