N2 - The ratcheting behavior of pressurized corroded straight pipe subjected to cyclic bending is investigated using Chaboche model in the paper. The effects of defect length, depth and width and internal pressure on ratcheting strain are studied. The results show that the ratcheting strain increases with the increase of defect length L/D depth H/T circumferential length and internal pressure. Moreover, in order to analyze the effect of defect size on ratcheting strain of corroded straight pipe pipe, calculation schemas are established according to orthogonal design method (ODM). Finally, dimensionless relations of both circumferential and longitudinal ratcheting strains to defect length, depth, width and internal pressure are established based on the multiple regression method.
