Abstract

Gupta & Tanabe(l997,1998) had proposed unified concrete plasticity model that can simulate stress-strain in both tensile and compressive region appropriately. It is realized that this type of model, where classical plasticity approach is implemented with only one damage parameter, cannot simulate stress-strain under cyclic conditions. In this paper, it is proposed to analyze the possibility of use of multiple damage pa- rameter to simulate stress-strain under such cyclic conditions. Few cases of uniaxial and biaxial cyclic cases of stress-strain situations are studied to demonstrate the possibility of the development of multiple damage model.
