Abstract

Abstract

Damaging effects of blast waves on tempered glasses were experimentally investigated to explore the blast damage threshold of the tempered glasses. The blast shock wave parameters were tested in each experiment, and the experimental overpressure-time histories were obtained. By analyzing the experimental data, the blast shock wave parameters were obtained, such as normally reflected overpressure, arrival time of the shock wave, duration of the normally reflected overpressure, normally reflected impulse, negative reflected overpressure, duration of the negative reflected overpressure, and negative reflected impulse. Compared with the results computed by the CONWEP program, the relative errors were small, which verified that the tested results were accurate and reliable. Meanwhile, the normally reflected parameters are greater than the corresponding negative reflected ones.
