Numerical modeling of carbides behavior under high-energy liading

Abstract

The results of research on modeling thermodynamic parameters ofshock-wave loading of carbides with different stoichiometric ratios arepresented. The carbides are considered as a mixture of carbon with thecorresponding component. The calculations of pressure, compression andtemperature values under shock-wave loading for solid and porous carbides inthe range of pressure values above 3 GPa are performed. The modelcalculations are compared with the known experimental results on theshock-wave loading of carbides with different porosity values. Thepossibility of modeling the behavior according to the proposed method forcarbides for which there are no experimental data at high dynamic loads isshown.
