运用文献 [1]中的变形模型和应力计算结果 ,推导出了存在热残留应力时的拉伸和压缩弹性模量和屈服强度表达式 ,表达式与试验吻合很好。分析表明 ,纤维根区域的压缩残留应力造成弹性模量的不对称性 ,基体拉伸残留应力和纤维的压缩残留应力造成屈服强度的不对称性 Using the deformation model and the stress calculation results in [1], the expressions of tensile and compressive elastic modulus and yield strength in the presence of thermal residual stress are deduced. The expressions agree well with the experimental results. The analysis shows that the compressive residual stress in the fiber root area causes the asymmetry of the elastic modulus, the tensile residual stress of the matrix and the compressive residual stress of the fiber, resulting in the asymmetry of the yield strength
