| 摘 要： | 发展了文献[1]中提出的变形模型, 研究了短纤维增强金属基复合材料热残留应力的分布及其对拉伸和压缩载荷下应力分布的影响。研究表明, 在拉伸和压缩载荷下, 热残留应力可导致不对称的应力分布和基体塑性, 热残留应力降低拉伸时的应力传递, 加强压缩时的应力传递。

| Abstract: | Thermal residual stresses and their effects on the stress distributions under the applied tensile and compressive loadings were studied by using the deformation model proposed in paper[1]. It was demonstrated that the residual stresses in the matrix and the fiber can reach considerably high magnitudes and result in asymmetrical stress distributions and matrix plasticity under the applied tensile and compressive loadings. Thermal residual stresses reduce the stress transfer in tension and enhance the stress transfer in compression. |

| Keywords: | metal matrix composites thermal residual stresses stress distributions |
