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
