Low Energy Impact Loading of Graphite-Epoxy Plates.

Abstract

An experimental and theoretical analysis was performed on low energy impact loading of thin (.040 inches) graphite-epoxy plates. Six-inch square plates were subjected to dynamic impact (below the ballistic range) and static loading. The plate static strain energy and dynamic impact energy for failure were equal and constant. Theoretical analysis was performed using both exact and finite element methods. Small deflection theory was assumed and found to be inapplicable; the plates behaved in a manner indicating that a large deflection theoretical model would be more appropriate. (Author)
