Abstract:Existing constitutive models rarely considered the effect of transition point from the strain-softening phase to the strain-hardening phase. In this paper, a new phenomenological model is proposed. The model introduces a transition optimization factor to take the effect of the transition point into consideration. The tensile and compressive deformations under different loading conditions are analyzed separately and compared with the results of the DSGZ (Duan-Saigal-Greif-Zimmerman) model. The results indicate … Show more
