Numerical simulation of strain threshold of monolithic tempered glass under blast wave

In this study, based on ANSYS/LS-DYNA, we described the tempered glass using the Lagrange method, reasonably simplified the blast wave load by simulating the failure of the tempered glass using the erosion algorithm, with the maximum elongation line strain theory used as the failure criterion for the monolithic tempered glass. We then simulated the monolithic tempered glass under the blast wave using model thus established. Through a large number of debugging and calculations, we identified the strain threshold of the failure of the monolithic tempered glass as 0.002 2. The numerical results were verified by the experimental results and proved as reasonable.
