| Abstract: | A method of calculating the deformation of a sphere as a result of divergent or convergent detonation of an explosive is presented. This method bases on the conservation of mass and momentum. and assumes the sphere material is incompressible and rigid plastic.The accelerated movement of a sphere calculated with this method is in good agreement with the experiment and the numerical result performed with the finite element hydrocode DYNA. |

| Keywords: | detonation projection rigid plasticity spherical shell. |
