doi:10.3969/j.issn.1000-1093.2017.07.019

Abstract

Abstract: Based on LS-DYNA, the Lagrange method is used to describe the monolithic tempered glass. The linear elastic material model and the erosion algorithm are used to study the monolithic tempered glass. The numerical model is well validated by the field experimental results. The overpressure-impulse curve of blast wave on monolithic tempered glass is obtained through the huge numerical simulation based on the validated model. The empirical formula of damage curve of monolithic tempered glass is also deduced, and the numerical results are compared to the experimental results. The research result shows that the numerical results have good agreement with the experimental results, and the overpressure-impulse curve can provide effective reference for blast resistant design of tempered glass.
