Constitutive model, failure mechanism and numerical method for reinforced concrete under intensive impact loading

Reinforced concrete has been widely used in the field of civil engineering, and the dynamic mechanical behavior of reinforce concrete under intensive dynamic loading is also a very important requirement for national security. However, the characteristics of its heterogeneity, anisotropy and multicomponent bring many difficulties to the study of its dynamic characteristics. Research progress of mechanical behavior of the reinforced concretes under intensive impact loading were reviewed in this paper, including: 1) the dynamical properties and the macrosopic constitutive laws of the reinforced concretes; 2) mechanisms of the penetration of the reinforced concrete structures; 3) numerical simulation method and software of structural mechanical behavior under intensive impact loading. On this basis, the inadequacy of the research which including the dynamic characteristics, penetration mechanism and numerical methods of the reinforced concretes under intensive impact loading were analyzed, and the further in-depth research work need to do in the future was prospected.
