Abstract

Abstract

In order to explore the hysteretic constitutive relationship of TA2/Q235 titanium-steel clad plates under cyclic loading， a total of 28 titanium-steel clad plate specimens under various loading protocols were tested. The monotonic behavior， hysteretic behavior， and fracture morphology of the specimens were obtained. The hysteretic curves of the specimens subjected to cyclic loading were plump without obvious pinching effects， demonstrating a mixed hardening characteristic combining isotropic hardening and kinematic hardening. Microvoid coalescence fracture， a typical mode of ductile fracture， was observed from the fracture morphology. The skeleton curves of titanium-steel clad plates were fitted using the Ramberg-Osgood equation， while the Chaboche plastic constitutive model was used to characterize the hysteretic behavior of the specimens. Based on the experimental results， the material parameters for both the skeleton curve model and hysteretic constitutive model were calibrated. The effects of the cladding ratio were examined using the calibrated hysteretic constitutive model. The results showed that the isotropic hardening effect of the titanium-steel clad plates became more significant with a decreasing cladding ratio， while the kinematic hardening characteristic remained unchanged. Using the ABAQUS finite element software， a numerical simulation of the cyclic loading test process was conducted. The simulation results agreed well with the experimental hysteresis curves， indicating that the calibrated parameters accurately predicted the response of titanium-steel clad plates under cyclic loading.
