| Abstract: | The paper is mainly about FEM analysis on the strain release factors for measuring residual stresses for composite materials using blindhole 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. |
