摘要
This paper presents a boundary element formulation for the computation of moments and stresses at internal and boundary points of laminated composite plates. Integral equations for second transversal displacement derivatives are developed and all derivatives of the fundamental solution are computed analytically. These integral equations are used to compute moments and stresses at internal points. Stresses on the boundary are computed by a procedure that uses integral equations for the first transversal displacement derivatives, derivatives of shape functions, and constitutive relations. The obtained results are in good agreement with finite element results available in literature. (C) 2010 Elsevier Ltd. All rights reserved.
