The mathematical model of perforation without detonation metal shell of explosive object by continuous laser radiation
The mathematical model of without detonation destruction of the explosive object metal shell by laser melting and softening of the shell by radiation with its subsequent break from the inside pressure of the explosives combustion products. The results of mathematical modeling of the process of exposure to continuous laser radiation with a power of 5 kW on a metal shell, with a wall thickness of 3 mm of explosive object with a melting type of explosive - trinitrotoluene, are presented. The simulation is based on the solution of the thermal problem by the finite difference method. It is established that the process of without detonation laser neutralization of an explosive object due to the action of the internal pressure of gases is achieved during exposure to radiation of 660 ms.
