摘要
采用 Muskhelishvili复势理论和 Riemann-Hilbert 问题的解法,给出了裂纹表面受伪集中力作用时的基本解。并利用“伪力法”和叠加原理给出了含中心斜裂纹的岩石类材料在压缩荷载作用下的应力强度因子的解法,分析了裂纹方向对应力强度因子的影响。利用基本解和边界条件可以计算板长和板宽对应力强度因子的影响。
The fundamental solutions for a crack under concentrated pseudo-traction are given by using the Muskhelishvili's complex potential theory and by the solution of Riemann-Hilbert problem. With the aid of the 'pseudo-traction' method and the superposition technique, the stress intensity factors for materials such as rock with center inclined crack under compressive load are determined and the effects of crack direction on the stress intensity factor are analyzed. The effects of finite length and finite width on the stress intensity factor are achieved by using the fundamental solution and the boundary condition.
