Numerical Simulation Study of Effects of Crater Formed by Explosion in Soil Medium with Cylindrical Charge
This paper points out that in explosive cases,in order to facilitate the packaging and conceal the eyes and ears,the explosive packaging used by criminals is of ten bottles,cans and other cylindrical bodies;soil is a common medium at the explosion site,and the effects of crater formed by explosion in soil medium is of great significance to criminal technical work such as the reconstruction of the scene of the explosion.In order to study effects of crater formed by explosion in soil medium with cylindrical charge,through dimensional analysis method,it is obtained that the scaled diameter and scaled depth of the crater under certain conditions are binary functions of the scaled radius and scaled burial depth of the explosive,and the explosion process of cylindrical charge with different scaled radius and scaled buried depth is simulated by LS-DYNA,according to the obtained simulation experimental data,the function relationship is fitted,and finally the relationship between the diameter of the explosion throwing action,the real depth of the crater,the radius of the charge and the buried depth of the explosive is finally restored.
