Abstract

Abstract

Based on ANSYS/LS -DYNA, the ALE method was used to describe the explosive and the air flow field, and the Lagrange method was used to describe the glasses.And the tensile stress failure of the glasses was considered as well as the shear -strain failure criterion.The corresponding calculation models and parameters were given for three kinds of architectural glass, respectively.Moreover, the numerical simulations were carried out to analyze the action processes of the explosion shock waves on the toughened PVB -laminated glass, the common PVB -laminated glass and the float glass, respectively.And the anti -explosion experiments were performed on these three glasses to compare with the numerical simulations.The comparisons show that the numerical results can reflect the punching failure phenomena of the glasses in the experiments.When the glasses occur to failure, their shock wave overpressures by numerical simulation are in agreement with the experimental results.Furthermore, the investigated results display that the toughened PVB -laminated glass has a higher explosion resistance than the common PVB -laminated glass and the PVB in the laminated glass can effectively prevent the glass from splashing.
