Reduced integral scheme of damaged divided back stress elasto plastic model based on full implicit algorithm

Abstract

The purpose of this study is formulating the reduced integration method of damage elasto plastic constitutive model with divided back stress based on full implicit framework. In the present formulation, after indicating elasto plastic constitutive model with damage divided back stress, the reduced return mapping equation with consistent tangent stiffness is introduced. The proposed formulation is tested in tensile hole plate and cyclic bending bar for verification.
