The paper has studied the numerical solving process of vaiiational pro blems associated with the geometric nonlinear bending guestion of plates and shallow shells. Firstly, a transform formula of domain and functional is given. Secondly, the numerical solving process of variational problems is presented and the general computational schems are given. Finally, some numerial examples are studied.The process in the paper is adaptable to engineering application
