摘要
The secondary damage effect of tempered glass subjected to blast shock waves was researched through experiments, and the statistics of mass distribution of glass fragments were done in the experiments. The mass distribution of fragments is analyzed and researched according to the statistical results. A dimensionless function of the relationship between the fragment mass and the splashing distance is derived based on the dimensional analysis. According to the dimensionless function and the experimental statistical data, a semiempirical prediction formula to calculate the fragment mass distribution is obtained by employing the least square fit. The characteristics of the formula are analyzed, and its reasonableness and effectiveness are verified. The research result shows that the mass distribution laws of glass fragments are consistent for the tempered glasses with the same thickness in the same damage mode.
