摘要
金属基复合材料的基体蠕变特性在一定的温度与应力下表现明显，当界面为非理想并具有粘弹性性质时，其对复合材料的整体蠕变亦有重要影响．本文利用具有非理想界面的复合材料的Ｍｏｒｉ－Ｔａｎａｋａ方法，研究了既具有基体蠕变又具有界面轻度蠕变的复合材料的本构关系。
Under certain temperature and stresses metal matrix composites can exhibit pronounced creep deformation When the interfaces of composite are imperfect and viscoelastic, they also considerably contribute to the global creep behavior Based on the Mori Tanaka method for composites with imperfect interfaces, this paper studies the constitutive behavior of the composites with both matrix creep and slight interface creep The effects of various microstructural parameters are carefully examined
