Reinforcing design for the opening on a certain experiment-used spherical explosive containment vessel was carried out referring to the pressure vessel code GB150-2011. The relationships between the effective plastic strain around the opening and the geometrical parameters of the nozzle and the reinforcing ring were investigated by numerical simulation. And a reinforcing scheme was proposed which included a nozzle with the wall thickness equal to 5/3 times of the wall thickness of the main spherical shell and a 10°-reinforcing ring with the same thickness to the main spherical shell wall. Experiments were performed to validate the reliability of the simulation results and the rationality of the reinforcing scheme.
