Shakedown of pressure vessel components under cyclic loading

Sabitov M.K., Ponikarov S.I.

Abstract


The limiting load is determined on the basis of the shakedown of structures in cyclic loading, by means of Melan’s theorem and the finite-element method in a shell formulation. For the example of a cylindrical vessel with a branch pipe under cyclic internal pressure, the formulation of the finite-element model and the solution algorithm is considered.
