Research on Damage Plastic Calculation Method of ABAQUS Concrete Damaged Plasticity Model

Ming Cao

Abstract

The large universal finite element software ABAQUS has been widely used in nonlinear analysis of reinforced concrete structure.Concrete Damaged Plasticity(CDP) is one of the most important concrete constitutive model in ABAQUS.This paper summarizes the principle and features of the model through theory inferential reasoning and analysis,determines the computational method of concrete damage plastic factors in ABAQUS.To validate this method,a finite element analysis of reinforced concrete simply supported beam is also presented.
