Abstract:

This report describes basic experimental and theoretical investigations of the interaction of projectiles and lightweight armor. The armor of interest is a very hard and relatively inflexible facing plate ceramic bonded to a flexible backing plate fiber glass or aluminum alloy. The theoretical work concerns 1 development of an analytical model for describing the restraining mechanisms of the armor and for prediction of ballistic limits, 2 checkout and use of a simple computer code for obtaining stress fields in brittle facing plates and projectiles caused by impact at normal incidence. The experimental work concerns 1 the use of high-speed photography and flash X-ray techniques for specific investigations such as observing fracture conoids in facing plates, 2 demonstrating that stresses in ceramic facing plates can be measured by manganin stress gages.
