摘要

In boundary element analysis if the internal point coincides with the boundary nodes, which is usually required for the problem with holes, the associated integrals may become singular. Although this problem has been well treated for two-dimensional or plate bending analysis, no report can be found for the coupled stretching-bending analysis of unsymmetric composite laminates. To avoid the singular problem, in this paper the components of stress resultants, bending moments, in-plane strains and plate curvatures in the tangential direction are suggested to be calculated by finite difference method, whereas the components in normal direction are calculated with the aid of constitutive laws. To prove the correctness of the proposed calculation method, a simply supported unsymmetric laminate with two rectangular holes is analyzed and compared with the results obtained by finite element method.
