Boundary element method for model analysis of 2-D composite structure

摘要

The boundary element method is used for he modal analysis of free vibration of 2-D composite structures in this paper. Since the particular solution method is used to treat the terms of body forces (inertial forces) in the equation of motion, only static fundamental solutions are needed in solving the problem. For an isotropic cantilever beam, the numerical results obtained by using the BEM presented in this paper are in good agreement, with those of using FEM or other BEM, but this BEM can also be used to analyze problems for anisotropic materials.
