| Abstract: | Describes experiments about the dynamic response of cast TNT by a light gas gun. With these experiments, were measured the Hugoniot curve and dynamic constitutive behavior of the cast and the Hugoniot curve and Murnaghan state equations were obtained.By selecting Bodner Perzyna constitutive model as the constitutive equation for cast TNT fitting the parameters of Bodner Perzyna constitutive model and the cast TNT constitutive equation is obtained.With the DYLA program,the process is simulated and the feasibility of application of the Lagrangian analysis is verified. |
| Keywords: | cast TNT impact experiment Lagrangian analysis constitutive relation |
