Abstract

Influence of creep on cyclic loading behaviour of thick cylindrical vessels is studied in this paper. The cyclic loading response of cylindrical vessels under load and deformation controlled cyclic loading is compared for the cases where creep is included and excluded. Kinematic hardening theory of plasticity based on the multi-linear Prager and Armstrong–Frederick models is assumed to evaluate the multi-axial non-linear strains in the plastic region. An iterative incremental method is proposed to solve the governing equations due to the non-linearity and load history dependency of the problem. Based on the obtained results an interaction diagram is proposed to predict ratcheting or shakedown behaviour of the thick cylindrical vessels.
