摘要
视基体材料为各向同性非线性蠕变体;纤维材料为各向同性线弹性体,基于Aboudi胞元模型对纤维增强复合材料的蠕变特性进行了细观分析.提出并用蠕变面函数讨论复合材料的正交各向异性蠕变流动特性.
Based on the acceptable assumptions that base materials exhibite isotropic creep flow and fiber materials behave elastically,the creep characteristics for fiber composites with the model of micromechanical analysis proposed by Aboudi are obtained.It is concluded that hydrostatic stresses produce creep deformation,a 3 D function of creep surface is developed to describe the orthotropic properties of creep flow in fiber composites.
