Response of Materials to Impulsive Loading.

Abstract

This report describes work conducted on the response of composite materials to foreign object damage. The damage inflicted to both metal matrix and resin matrix composites was investigated by measuring the post impact residual mechanical properties of selected materials. Specimens were mounted as simply supported cantilevered beams and impacted with steel or rubber spheres. The residual tensile and fatigue strength of the material was then determined. The impact resistance of the composites investigated was shown to be much lower than that for titanium. The important mechanisms of material damage were identified and described in terms of a fracture mechanics based model. (Author)
