Abstract
The paper presents a solution to the centrally symmetric problem of determining the velocity field in a continuous elastoplastic medium during a camouflet explosion, assuming that the motion of the camouflet cavity is non-oscillatory and that the medium is incompressible in both the plastic and elastic regions. Dependencies for determining the size of the expansion zones and plastic deformation of the medium are obtained. The solution is based on the “camouflet equation” — a relationship for determining the pressure on the contact surface of the expanding spherical cavity due to internal pressure.
