摘　　要：讨论了小孔法测量正交各向异性材料残余应力。以正交各向异性无限大板孔边应力场解析解为基础，导出了释放应变矩阵计算表达式，并用一个算例验证了该计算式的正确性。The hole drilling method is presented to measure residual stresses in orthotropic materials. Based on the analytical solution to stress field around a hole in a stressed orthotropic infinite width plate, a set of equations was derived to calculate the relieved strain matrix. An example was given to assess the validity of these equations.
