【Abstract】 A new method of computing elastic tensor of material with microstructure is presented based on the homogenization method. The control equation of microstructure with a hole without external load is developed. The formulation of computation elastic tensor using the perturbation method and the schemes to solve this problem using finite element method are given.更多还原
