Blast Blast Computer Simulation

Code for Blast Analysis using MatLab

Abstract

Shock waves generated by explosions move at supersonic speeds with great pressure and temperature, and not only incapacitate military and civilians, but also damage buildings and nearby areas. In many cases, damage can lead to the total or partial collapse of the target building and other facilities close to it. There are several programs for blast analysis, however, obtaining such licenses is almost impossible in countries with limited research resources. Thus, the purpose of this article is to present a MatLab code developed for blast analysis using the Finite Element Method. The code was developed for numerical analysis of air burst and hemispherical surface burst using an equivalent quantity of TNT, based on the Kingery-Bulmash equations. Numerical results were compared with experimental data from others researches with great convergence.
