Introduction to Abaqus Explosion package
To introduce the Abaqus Explosion package”, firstly, we are going to describe the explosion. An explosion is a rapid expansion in volume associated with a hardly vigorous outward release of energy, usually with the generation of high temperatures and the release of high-pressure gases.

This tutorial is an elementary level of explosion theories and if you want to learn more about the supersonic explosion or subsonic it is needed to use an advanced training package of explosion. In the below paragraphs, you see a brief explanation of workshops.
Workshop 1: Explosion against a brick wall
In this simulation, an explosion over the brick wall has been analyzed.
Dynamic explicit is appropriate for this type of analysis. To have the right model, it is needed to define special boundary conditions in this problem. Also, explosion loads having special amplitude are used to model explosion.
Workshop 2: underwater explosion
This example demonstrates how ABAQUS can be used to predict the long-duration response of submerged structures that experience loading by a wave resulting from an underwater explosion (UNDEX). The model is supposed to have damage with regard to explosion effects and plastic strain and ductile damage is used in modeling to demonstrate a realistic behavior. A special boundary condition is necessary to define the explosion phenomenon correctly.
