A new boundary element formulation for shear deformable shells analysis

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 ex- ternal 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 nite element method
