000013763 520__ $$2eng$$aIndustrial piping can be subjected to severe cyclic loading associated to temporary ground deformations induced by seismic activity. One of the reasons of piping failures under earthquakes can be identified in the accumulation of plastic strains along with biaxial ratcheting of elbows subjected to in-plane cyclic bending. This paper deals with the estimation, using finite element analysis, of the strain evolution in a representative OD 8” X52 grade piping section including an elbow subjected to cyclic in-plane bending and internal pressure. Lemaitre-Chaboche nonlinear kinematic hardening model for plasticity has been employed in FEA to represent the ratcheting phenomenon more efficiently with respect with standard kinematic hardening rule. Numerical results provide an estimation of the plastic strain evolution at critical locations, which may result in crack formation or material damage, and valuable information to address a full future scale testing program that will be undertaken within the INDUSE project
