摘要：
A new domain-boundary element formulation to solve bending problems of shear deformable shallow shells having quadratic mid-surface is presented. By regrouping all the terms containing shells curvature and external loads together in equilibrium equation, the formulation can be formed by coupling boundary element formulation of shear deformable plate and two-dimensional plane stress elasticity. The boundary is discretized into quadratic isoparametric element and the domain is discretized using constant cells. Several examples are presented, and the results shows a good agreement with the finite element method. Copyright (C) 1999 John Wiley & Sons, Ltd.
