Numerical Study of Effective Elastic Properties of HGB Periodically-Reinforced Composite

Representative volume element methord is used to simplify HGB (hollow glass bead) periodically-reinforced composite model into representative volume element. Orthotropic properties and change rules of effective elastic constants (modulus and Poisson's ratio) and HGB wall-thickness of representative volume element are studied by using the finite element methord. The study finds that there is no obvious difference of each direction of the three kinds of composites with different filling types; the effect of filling type is not very obvious also.
