Findings of the experiment-calculated investigation of the stress-strained state and strength of metal explosion chambers of cylindrical and spherical types with a diameter of 2-10.5 m which are intended for multiple blastings of charges with different weight are presented. To evaluate the stress-strained state, the finite element method in the elastoplastic setting and tensometry were used.
