Plate Modeling under Blast Loading By Brian Cabello

Problem Statement This project will focus on the analysis of how different blast loading (shock wave) affects a plate of High Ductility Stainless Steel Alloy (Al- 6XN).

Blast wave propagation

Blast wave propagation con’t It is known that 1 kg TNT releases the energy of 4.520x10 6 J. The effects of an explosion can be distinguished in three ranges: – Contact detonation: The explosive is in contact with the loaded material. The load-time function depends on the loaded material, which, in most cases, is destroyed. Occurrences are the blasting of concrete (demolition etc.) or terrorist attacks where the explosive is located directly on the structure. – Near zone of the explosion: In most cases the material is also directly damaged like in the contact zone. – Far zone. The blast wave resulting from the detonation dominates the effects on humans and structures. The size of all these zones depends on the quantity of the explosive charge.
