Quasi-Static and Dynamic Ballistic Damage Mechanisms in Confined Ceramic Tiles
D. ShermanDepartment of Materials Engineering, Technion, Israel Institute of Technology, Haifa 32000, Israel
Abstract
Quasi-static and dynamic damage mechanisms in alumina tiles were investigated. The tiles were under a variety of boundary conditions at the tile's edges during impac. NATO 0.3 cal. AP rounds with hardened and sharpened steel core were used. The alumina tile samples were 50x50 mm2 area, the thicknesses ranging from 5 to 12 mm. The tiles were mounted in a special confinement frame, which enabled to investigate the failure mechanisms under a large variety of boundary conditions. Steel and Spectra composite were used as backing plates, for their distinct modulus of elasticity and acoustic impedance. Three different support configurations were used : semi-infinite, thick walled, and simply supported.
