Abstract: Blasts are not always caused by combustion; they can also result from any rapid release of energy that creates a blast wave, such as a bursting pressure vessel from which compressed air expands, or a rapid phase transition of a liquid to a gas. The loads resulting from a blast are created by the rapid expansion of the energetic material, creating a pressure disturbance or blast wave radiating away from the explosion source. Blast pressure is more properly called overpressure because it is relative to ambient conditions. Shock waves are high-pressure blast waves that travel through the air at a velocity faster than the speed of sound. These waves are characterized by an instantaneous increase in pressure followed by a rapid decay. The blast loads are applied per millisecond, so it needs a dynamic structure analysis and for economic design it accept cracks and deformation so it needs a non linear analysis also with the dynamic effect.
