Abstract
In this paper the experiments of static buckling behaviour and post-buckling dynamic behaviour of clamped shallow spherical shells under external pressure by Yainada are simulated by FE analysis. A locking free 9-node-shell element by mixed variational formulation previously discussed by authors is used The good agreements between static buckling behavior of experiments and that of FE analysis are obtained not only buckling pressures but also displacement distributions. Also the good agreements between post-buckling behaviours are obtained by using an external viscous damping modeling.
