Abstract

Based on the asynptotical perturbation method and the Galerkin Itechnique.thehybrid changeable basis Galerkin technique is presented for predicting the nonlinear response of structures.By the idea of changeable basis functions first proposed,itgreatly reduces calculation and is easily used in other numerical diseretization techniques,such as finite element method etc.,It appears to have high potential forsolution of nonlinear srtyctyrak oribkrbts.Finally,the effectiveness of this technique isdemonstrate by means of two numerical examples:the large deflection of circularplates objected to uniform normal load and the large deflection of spherical caps under centrally distributed pressures.
