【摘要】 本文运用均匀化方法计算双向铺层复合材料层板等效弹性参数时,进行了适当地处理,推广了单层板情形的做法。同时在预估的等效弹性参数基础上,对其刚度进行优化设计,结果证明本文方法的合理性。
【Abstract】 This paper discusses the homogenization method to determine the effective average elastic constantsof bi-angle-ply laminate by considering their microstructure.the finite element method is combined withhomogenization theory for predicting the properties of composite materials.After obtained predicting elasticconstants,the stiffness optimum design is also studied in this paper,the result of this method is accordance tothose in others.
