Application of homogenization method in prediction of elastic and natural frequency optimal design for bi-angle-ply laminate

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.
