A Concrete Constitutive Relationship With Various Damage Models

China Civil Engineering Journal. 2003. 36(11). 70-74.

Abstract: A concrete constitutive relationship with various damage models is developed in this paper. The failure models of concrete are divided into several zones according to the principle stress ratio. Different loading/unloading behaviors and nonlinear indexes are applied to various zones. So the behavior of concrete under disproportionate loading conditions can be simulated better. Both fixed crack model and rotating crack model can be considered in this model for the complex fracture of concrete. This paper also introduces the method to embed this concrete model into the FEA software of MSC.MARC with the secondary development function of MARC. Numerical examples are shown to illustrate the advantage of this model on some complex problems.
Keywords: nonlinear finite element analysis; concrete; constitutive relationship; secondary development
