Behaviour of cylindrical steel drums under blast loading conditions with SPH method in Abaqus

In this tutorial Behaviour of cylindrical steel drums under blast loading conditions with SPH method in Abaqus has been investigated. In the last few decades, a number of major industrial accidents have occurred around the world.The blast wave of detonation has a sudden rise in pressure above atmospheric conditions to a peak over pressure (free-field or side-on). The peak over pressure gradually decays to ambient pressure, followed by a small negative phase. Deflagration typically produces a blast wave with a gradual over pressure rise to peak value followed by a decay and a negative phase with similar scale to the incident positive phase. Generally, detonation produces a blast wave with higher peak over pressure but shorter positive duration than in a deflagration case. Deflagration is able to transform into detonation within a highly congested region. When a detonation blast wave impinges on a surface, it is reflected. The magnitude of reflected over pressure depends on the peak incident value and angle of incidence. For deflagration, the reflected over pressure is more closely related to the parameters of incident wave and dimensions of the target. It does not have a significant enhancement as normally expected from a detonation blast wave at the same level of peak incident over pressure. The schematic of geometry has shown at below

During the analysis blast wave pressure causes a huge deformation on drum and because of this it the water inside the tank were be wavy like sloshing phenomenon. To model drum behavior under blast load Johnson-Cook plasticity and damage and for water Us-Up linear form has been used.You can see some figures of this simulation at below
