Formulation of 3-D Homogenization Method for Fabric Composite Laminates by Considering the Effect of Finite Thickness

Abstract

Microstructure of fabric composite laminates can be very complex. Modeling such microstructure by using representative unit-cell requires assurance of periodicity. In that case, homogenization theory, a rigorous analytical method that considers periodicity, is often employed. Homogenization theory also considers both microscopic and macroscopic deformation of the unit-cell. The unit-cell model of fabric composite laminates is often considered to be periodic in three-dimension. However, in reality, composite laminate is very thin. Therefore, the effect of finite thickness must be taken into account. In this regard, unit-cell should be assumed to have finite thickness. It can be achieved by releasing the boundary condition in thickness direction. This paper deals with theoretical treatment of the modified 3-D homogenization method considering the effect of finite thickness.
