A Viscoelastic Continuum Damage Model for Reinforced Concrete Subjected to Shock Loading
In this paper, we analyze a RVE of concrete reinforced (RC) with steel reinforcing bar in two vertical directions on basis of the thoughts of composite material and propose that in the ideal case the constitutive equation of reinforce concrete is declared to multiply the viscoelastic constitutive equation of concrete by a reinforcing multiplier G , which is depended on material characters and arrange mode of steel reinforcing bar. In the model, we draw the growing damage law on the assumption that damage only occur in the concrete. Subsequently, we obtain the damage viscoelastic constitutive equation of reinforced concrete. Lastly, the comparison with the plate impact test results of specimens shows that the proposed model can give consistent prediction of the dynamic behavior of SFRC.
