Explicit Finite Element Methodologies for Simulating the Mega-Hertz Plate and the Ballistic Shock Simulator

Abstract

Modem armored vehicles are equipped with a variety of sensitive components on board, such as computers, telecommunication equipment, range finders, and infrared devices. One potential failure to these sensitive electronic components is due to the high frequency shock wave transmitted through the structure due to impact loads. Failure or malfunction of the electronic equipment can severely damage the combat capability of the armored vehicle, even though the crew survives and the vehicle retains its structural integrity after the impact. These impact loads can be from air blast, land mine detonation, or a projectile penetration. A good understanding of the loading functions due to blast, impact, and penetration, and the stress waves transmitted through the complex vehicle structure due to these impulsive loads, facilitates the improved combat capability of the armored vehicle. Advantages of each of the approaches will be presented, including a comparison of numerical simulations with experimental data.
