Study the response of materials under high pressure loading

Abstract

Materials which can absorb the high energy flow are of great importance. The high pressure waves, generated by an explosion or high impact loading, have a very high energy value and it causes a great damage to the objects which come in its path. Though every material, depending upon its properties, offers certain degree of resistance to the flow of energy, there are some materials which have the ability to absorb much more energy than others. These materials when combined together or when layered with other materials, can act as an entity which if suitably formed and placed, can resist the flow of high energy in a very effective manner. The research in the field of developing new materials and composites, is evolving as one of the promising research area in the field of material science as they can do wonders in saving precious lives and properties from the damaging effects of high pressure waves. In this paper the concept is presented by employing the high energy absorbing materials and their combinations (i.e. layered together), to study their effectiveness against the impact of high pressure waves produced by an explosion of TNT charge kept at a certain distance. Conditions have been simulated using ANSYS Autodyn software. Attenuation of high pressure waves is observed by studying the Energy absorption property of the materials as a key parameter. The deformation of the material plate and other associated parameters are also studied.
