Abstract

This paper presents a new engineering model on the air blast wave of TNT explosive. The model is built and the parameters are calibrated based on numerical simulated pressure time data of shock wave in air. The model describes the peak overpressure, impulse, typical time and attenuation coefficient of the shock wave with new computational equations. Comparison of pressure configuration for the scaled distance shows that the present engineering model can give consistent results with the numerical code and experiments. Keywords: blast wave, overpressure, numerical simulation, engineering model.
