Abstract
Abstract The micromechanical damage model proposed in Huang et al. (2002) [Huang C, Subhash G, Stanley JV. A dynamic damage growth model for uniaxial compressive response of rock aggregates. Mech Mater 2002;34:267–277] is modified to predict the dynamic damage evolution of concrete subjected to dynamic axial compression loads under different lateral confinement conditions. It shows that the stress–strain response, the compressive strength and the damage growth rate are strongly influenced by the confining pressure. It is also found that when the strain-rate exceeds 10 4 s -1 , the compressive strength tends to be greatly depended on strain-rates.
