Viscoelastic and Damping Properties of Armor Materials under Hypervelocity Penetration.

摘要

In this report, the theoretical and experimental verification of dissimilar modeling and scaling laws for a hypervelocity impact and penetration mechanism are presented. The impact test apparatus was designed, built and used for generation of the data for the verification of the scaling laws by means of dissimilar materials of the model and prototype. Two types of impact force transducers were developed, employed either membrane or segment of the tube as a sensing element. The second type occurred to be very effective for these applications. The results of computation and experimentation are presented. The developed method of an indirect measuring of the instantaneous penetration and penetration force was successfully used in this research. (Author)
