“…Unlike the ratcheting experiments carried out on the bar specimen in which the uniaxial tensile test method is used, most of the ratcheting experiments of internal pressurized pipes focus on the bending ratcheting behavior, such as cyclic three point bending (Scavuzzo et al 1991), cantilevered bending (Igari et al 1996). Ratcheting data of straight pipe under cyclic bending and steady internal pressure were developed at University of Notre Dame (Corona 1996), Wolters et al (1997) investigated the ratcheting phenomenon of the first wall of a fusion reaction for dominating bending loads, and experimental and theoretical studies on ratcheting were carried out. Krämer et al (1997) researched the ratcheting behavior of austenitic pipes.…”

With a quasi-three point bending apparatus, ratcheting deformation is studied experimentally on a pressurized austenitic stainless steel Z2CND18.12N pipe under bending load and vertical displacement control, respectively. The characteristic of ratcheting behavior of straight pipe under both control methods is achieved and compared. The cyclic bending loading and internal pressure influence ratcheting behavior of pressurized straight pipe significantly under loading control and the ratcheting characteristics are also highly associated with the cyclic displacement and internal pressure under displacement control. They all affect not only the saturation of the ratcheting strain but the ratcheting strain rate. In addition, ratcheting simulation is performed by elastic-plastic finite element analysis with ANSYS in which the bilinear model, Chaboche model, Ohno-Wang model and modified Ohno-Wang model are applied. By comparison with the experimental data, it is found that the CJK model gives reasonable simulation. Ratcheting boundaries under two control modes are almost same.
