Analyses and experiments were conducted to determine the dynamic response of rubber materials under impact loading. A mathematical model was developed that characterized the mechanical properties of the rubber bar material. The model is that standard linear model of linear viscoelasticity and is completely described by three parameters. The differential equations and boundary conditions that govern the response of the material to impact are presented and solved using the method of characteristics. Equations are derived to determine the energy loss of the method of characteristics. Equations are derived to determine the energy loss of the impacting projectile. Impact tests were conducted on the two different materials, Butyl 550 and Silicone G-46, and detailed test data is presented. Modified author abstract
