Constitutive model, failure mechanism andnumerical method for reinforced concrete under intensive impact loading
2016
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.
