对热膨胀失配引起的残余应力的计算原理和以往的解决方法进行了评述。提出了一个通用模型。考虑单向复合材料在轴向和横向方向上的有效热弹性性质允许更全面地处理纤维增强复合材料中的残余应力情况。参数的变化表明界面层的热机械性能的重要影响，这是在大多数传统的计算中被忽略。
Principles for the calculation of residual stresses due to thermal expansion mismatch and previous solutions are reviewed. A general model for this subject is proposed. Considering the effective thermoelastic properties of a unidirectional composite in axial and transverse directions allows a more comprehensive treatment of the residual stress situation in fiber-reinforced composites. Parameter variations show the important influence of the thermomechanical properties of an interfacial layer, which is disregarded in most of the conventional calculations.
