Parametric Identification of the Degenerate Model with a Dissipative-Elastic Element Dispersing Impact Energy
The article discusses the issues regarding the identification process of the ballistic impact on a shield of composite construction. Using a mathematical model of the phenomenon of piercing the material with a bullet fired from a firearm, it has been assumed that the resisting force F of the material is described by a non-linear function consisting of the elastic element and the dissipative element. Identification equations have been derived for specific structures of the model. The studies related to the response of the model to pulse load have been conducted by numerical simulations the results of which have been verified by the tests conducted in a shooting range.
