Analysis of Composite Materials by a Hybrid FE-BE Method.

Abstract

The hybrid finite element-boundary element method was applied to solve the two dimensional problem of composite materials. The method combines the differential and integral approaches and gives specific advantages to analyze the system which includes different materials. In this paper, the base matrix of the composite material was modeled using the boundary element method, while the fibers imbedded in the matrix were represented using the finite-element method. Two-dimensional elastic problems were solved to demonstrate the effectiveness of this method in the analysis of composite materials. It was shown that the solutions with high accuracy can be obtained by the hybrid FE-BE method using far smaller degrees of freedoms compared with the finite-element method.
