“…Figure 6 shows the corresponding particle velocity and strain profiles. 5 Initially, both velocity and strain are zero along the entire length. As time increases the left end of the specimen is accelerated in the negative x direction causing the particle velocity and the strain to increase near the impact end.…”

“…A similar problem arises in transparent armor applications as well; transparency to visible and other wavelengths is essential in many applications and these transparent "ports" need to be protected against foreign object impact as well. There have been numerous studies of the dynamic failure behavior of ceramics used as transparent armor (see, for example [3,4,5]). Glass, laminated with alternating layers of polymers of varying thickness and fracture properties, is also a very commonly used as transparent armor [6].…”

Characterization of the Transient Response of Polyurea

The strain-rate dependent tensile response of a transparent elastomer, polyurea, is determined at stretchrates in the range of 800 to 8000 per second. This is accomplished by measuring the spatio-temporal evolution of the particle velocity and strain in a thin strip subjected to high speed impact loading that generates uniaxial stress conditions. The observed response is modeled using a modified viscoplastic constitutive relation.

Abstract. The paper presents numerical and experimental results in the study of composite armour systems for ballistic protection. The modelling of protective structures and simulation methods of experiment as well as the finite elements method were implemented in LS DYNA software. Three armour systems with different thickness of layers were analyzed. Discretization for each option was built with three dimensional elements guaranteeing satisfactory accuracy of the calculations. Two selected armour configurations have been ballistically tested using the armour piercing (AP) 7.62 mm calibre. The composite armour systems were made of Al2O3 ceramics placed on the strike face and high strength steel as a backing material. In case of one ballistic structure system an intermediate ceramic-elastomer layer was applied. Ceramic-elastomer composites were obtained from porous ceramics with porosity gradient using pressure infiltration of porous ceramics by elastomer. The urea-urethane elastomer, as a reactive liquid was introduced into pores. As a result composites, in which two phases were interconnecting three-dimensionally and topologically throughout the microstructure, were obtained. Upon ballistic impact, kinetic energy was dissipated by ceramic body The residual energy was absorbed by intermediate composite layer. Effect of the composite shell application on crack propagation of ceramic body was observed.
