In this paper, using the formal approach of asymptotic expansion for linear elastic shell we can get each term uk successively. According this method the leading term u0 will be identified by an elliptic boundary value problem, other terms will be obtained by the algebraic operations without solving partial differential equations. We give the variational formulation for the leading term U(x) and construct an approximate solution U^KT(x,ξ):= U(x) Ⅱ1Uξ Ⅱ2Uξ,then we give the estimation. 相似文献
