摘要
建立了一种细观力学模型用于预报复合材料的有效热膨胀系数。利用该一模型计算热膨胀系数无需对复合材料进行热应力分析，仅需知道在某一相关外力场作用下，其组分相内部的平均应力场问题即可解决。作为示例，本文得到了层合板及晶须增强金属基复合材料有效热膨胀系数的计算公式。
A micromechanical model was proposed to predict the thermal expansion coefficient of composite.If the average stress field in one constituent phase under the action of external load is known,the model can predict the thermal expansion coefficient without the need to consider the thermal stress.As an example, the equation for thermalexpansion coefficient of the laminate and the metal matrix composite were derived.
