摘　　要：对盲孔法测量正交各向异性复合材料残余应力释放应变矩阵进行有限元分析。以碳/环氧正交各向异性材料板为基础,对于不同孔深的盲孔进行有限元计算,得出与其相对应的释放应变矩阵,并分析孔深对释放应变矩阵的影响。为实际工程中残余应力的测试奠定了基础。The paper is mainly about FEM analysis on the strain release factors for measuring residual stresses for composite materials using blind-hole method. It is based on orthotropic plate , using the FEM to analyze the blind hole under different depths , relieving the strain matrix , analyzing the effects of each depth on strain matriX , thus provides the basis for practical projects in the future.
