Numerical Simulation of Double-Deck Metal Cylindrical Tube Crashed under Inside-Explosive Loading
To study the deformation and fracture form of double-deck metal cylindrical tube under inside-explosive loading，the numerical simulation of the deformation and fracture process of double-deck metal cylindrical tube under inside-explosive loading of TNT was performed by LS-DYNA, and the fragment number and mass statistics software code is developed. The results showed that, with different length of TNT and detonating position the fragment number and mass is greatly different . The result can be a consult to some practicalities like the cannonball exploded in the gun barrel during shoot.
