Abstract

Abstract

As an essential construction material, the tempered glass has important research value and engineering application background for study on the failure law and protective performance under accidental strong dynamic loads such as explosion, earthquake, collision and typhoon. Experimental investigations on the quasi-static and high strain rate mechanical properties of tempered glass were conducted with the MTS (materials testing system) and the split Hopkinson bar (SHPB), respectively. The parameters of the JH-2 constitutive model were calibrated and the model’s accuracy was verified. The simulation was conducted to investigate the failure processes of tempered glass panes under different overpressure peaks and different impulse shock waves with the LS-DYNA software. The failure scaled radius of the tempered glass pane is about Z=4 m·kg^-1/3. As the stand-off distance decreases, the pane tends to be safe; however, as this distance increases, the damage degree significantly rises. This indicates that, the failure of tempered glass panes depends not only on the peak overpressure but also on the impulse.
