【摘要】 基于均匀化方法对双向铺层复合材料层板等效弹性参数进行预估,通过均匀化方法有限元模型的分析,说明对双向铺层弹性参数单胞模型处理是合理的。在预估的等效弹性参数基础上,对其自振频率进行优化设计,结果表明文中方法是可行的。更多还原

【Abstract】 The finite element method is combined with homogenization theory for predicting the properties of composite materials. Discuss finite element model of the homogenization method to determine the reasonable of bi-angle-ply laminate by considering their microstructure. After obtained predicting elastic constants, the natural frequency optimal design is also studied in this paper, the result shows the method in this paper is feasible.更多还原
