Исследование ползучести пологих оболочек на базе уточненной теориии вариационно-структурного метода

Abstract

A creep problem for shallow shells within the framework of the refined theory is considered. The varia­tional formulating of problem is presented. The method of solving of initially-boundary creep problem is based on joint usage of the variational-structural method and the Runge-Kutta-Merson method. The solution structures, the numerical results for creep behavior and the lifetime predictions for spherical shallow shell with different boundary conditions are presented
