Determination of the Effective Modulus of the Syntactic Foam Containing Hollow Spheres by Differential Scheme and Mori-Tanaka Method

On the basis of differential scheme and Mori-Tanaka method,two methods are developed to determine the effective modulus of composite reinforced by hollow spheres with changing contents and changing ratio of inside and outside radii.Then,Multi-step homogenization technique is adopted to determine the effective modulus of multi-phase composite.By the two approaches mentioned above,the effective modulus of the syntactic foam containing hollow glass spheres are calculated. The results show that the theoretical prediction of the Young-s modulus is precise enough.The factors of hollow spheres that influence the composite modulus are analyzed.
