| Abstract: | A perturbational method based homogenization method is formulated to simulate the constitutive properities of three-dimenisonal braided composite materials by means of finite element models.The numerical tests of three dimensional braided composite structures are presented to show that more accurate results of effective modulus are obtained and little computer time cost comparing to other numerical methods. |
