NUMERICAL SIMULATION OF THE STAINLESS STEEL RHS MEMBER UNDER CYCLIC LOADING, IDENTIFICATION OF MATERIAL MODEL PARAMETERS, AND COMPARISON WITH HSS STEELS

Original language description

This study examined the cyclic behavior of stainless steel through a combination of experimental tests and numerical simulations. The study began with a comprehensive analysis of material properties and experimental configurations, which provided a solid foundation for developing a robust finite element (FE) model. A new simplified material model inspired by Ramberg-Osgood was developed for easy use in practical tasks. For example, the ANSYS software only offers the original Ramberg-Osgood model for monotonic loading and Chaboche model is not as easy to calibrate as the Ramberg-Osgood model which is defined by parameters which can be easily retrieved from coupon tests. The combination of the validation against experimental data and material model parameters identification using sensitivity analysis and mathematical metamodel confirmed that the model accurately reflects the material's performance under cyclic loading conditions. Further comparisons with high strength steels (HSS) underscore the superior performance of stainless steel when subjected to cyclic loading. These findings underscore the advantages of stainless steel in structural applications requiring high ductility, strain hardening, and resistance to cyclic loading. In conclusion, this research validates the effectiveness of the simplified material model and underlines the increasing use of stainless steel in contemporary structural engineering. Its distinct properties make it a valuable material, especially in many times repeated loading, where performance under cyclic loading is critical.
