Release of high pressure air due to some ignition of bombs and explosives that causes explosions is called as blast. Bombsare used in various works such as in construction of tunnels for road and railways, fattening of buildings so that new construction can take place. In some area explosions are used for creating terror among the citizen like terrorist use vehicle bombs, other places where explosions likely occur is in nuclear power plants where due to unsafe isolation could lead to devastating explosions. The paper presents a design concept for containment vessel that need to withstand internal explosions. ABAQUS software is used for numerical simulation of containment vessel. Parametric studies are carried out using the proposed model of containment vessel. It is observed from the studies that the pressure versus time, displacement versus time and the strain energy curve for blast containment vessel is obtained.
