Impact Behavior of Concretes Taking Account of Strain-Rate Effect, Stress-State Effect and Damage Evolution

Abstract:

Article Preview

At high strain rates, the dynamic response of concrete, a heterogeneous material with damage, was experimentally studied under (1) one-dimensional strain state at high pressures from 1 to 4 GPa by using a one-stage gas gun and (2) one-dimensional-stress state by using the SHPB technique. The main results are given and discussed. The results indicate that the effects of strain rate, stress-state and damage evolution should be considered in studies on the nonlinear impact behavior of concretes. A damage-modified visco-elastic model (ZWT model) is proposed for concrete C30.
