Advanced Physics-Based Analytic Modeling

Physics based analytic models are essential in some cases to understanding and addressing the complex nature of blast, shock, and impact effects for such phenomena as:

• Penetration of a projectile through a structural component or substance and the best way to prevent or mitigate such an event. Modeling offers a direct means to address the complexities associated with the impact/penetration events including the design of detonation shields.
• Response of a structural component to a contact or near contact charge. This kind of analysis must include fracture and other forms of extreme material changes due to the extremely high pressure loads involved.
• Simulation of the actual behaviors that occur in blast, shock, and impact events. Such simulations are important in performing the kinds of tradeoff studies needed to obtain cost effective designs.
• Typically, the analytic model represents a set of physics based algorithms coded into a software program and an input process that allows the user to characterize a specific system and load to be considered, and at what fidelity.
