Simulation of Air Blast Waves and the Loading of Glass Sheets

The behaviour of explosive can be regarded with different methods. A solid TNT model describes the explosive by solving a JWL Equation. An alternative method will be presented with a bubble with overpressure inside. This method will be compared with a solid TNT calculation and with experimental data. The calculation of an urban environment shows good correlation with experiments. The windows of trains are in most cases built with laminated security glass (LSG). There are different ways simulating LSG which vary in the number of elements through the thickness. The differences between a smeared model with two layers and models with three layers through the thickness loaded by an air blast load will be presented.
