This article compares isotropic and kinematic hardening rules for square hollow section (SHS) numerical modelling under cyclic bending loading. Hot-rolled and cold-formed SHSs are used. For the cold-formed SHS, the kinematic hardening rule produces hysteresis, which is consistent with the experimental results. However, for the hot-rolled SHS, which has a lower yield ratio, both isotropic and kinematic hardening rules are required. The isotropic hardening parameters for the hot-rolled SHS were obtained using several published equations, and the kinematic hardening parameters were obtained by fitting to existing data. A combined hardening rule was applied to the hot-rolled SHS model, and the obtained hysteresis was consistent with experimental results. The results provide insight into the behavior of hot-rolled and cold-formed SHSs. They can be used to select the hardening rules for cyclic behavior analysis. [ABSTRACT FROM AUTHOR] |
