Урахування геометричної нелінійності у розрахунках на повзучість тонкостінних елементів конструкцій

Abstract

In article the method of the solution of the initial-boundary value problems of the creep theory of shells of revolution is given, which one are constructed on the basis of finite element method (FEM) and equations of state with allowance creep-damage process. The shells with deformation of transversal shift and geometrical nonlinearity are reviewed at final normal displacements. The example of geometrically nonlinearity calculation is given
