摘要：
The boundary element method for the modal analysis of free vibration for 3-D anisotropicstructures using particular solutions has been developed.The complete polynomials of order two are used toconstruct the particular solutions for general anisotropic materials.The numerical results for 3-D free vibra-tion analysis of an isotropie cantilever beam by the method presented is in good agreement with the results us-ing the Ritz technique.For anisotropic materials,the numerical results calculated from the proposed methodare in good agreement with the results from MSC.NASTRAN.
