Abstract: The Taylor-Chen-Kuszmaul model，which is rate dependent and used to ceramic material，was modified and applied to glass materials so as to investigate the tensile damage characteristics of inorganic glass materials un- der impact loads． The modified TCK constitutive model was used to simulate the edge-on impact test of glass plate． Simulation results show that the modified TCK constitutive model can accurately simulate the propagation velocity of the stress wave，the size and location of the damage area，and the damage propagation velocity of glass materials．
