The effect of projectile travelling at Hypervelocity onto solid metal target

Abstract

This project is about to study the effect of projectile travelling at hypervelocity onto solid metal target. The method is used to control the projectile speed by using explosion in different mass of commercial explosive as an explosion material. The amount of explosive will give impact to projectile to accelerate at hypervelocity and hit the target after explosion happen. The parameter setting such as amount of explosive, material and shape of projectile, material of solid metal target and shaped charge play an important role to control the pressure after an explosion. The parameter also to ensure that the projectile accelerate at hypervelocity speed and hit the target well. ANSYS AUTODYN software is used to make the simulation and to identify the ideal parameter setting during conduct the real experiment. The simulation data also investigated by using theoretically and numerically method. Expected result is the crater occur at target surface is depend on the projectile shape. The ogive nose shape of projectile is more efficient compare to blunt and hemispherical nosed shape. Besides, the higher amount of explosive will generate the higher energy. Lastly, the design of projectile shape and high impact penetrator is used in simulation to obtain the information required in this project.
