Abstract:

The dynamic stress-strain of composite materials may be determined using Split Hopkinson Pressure Bar SHPB techniques. The method includes placing a composite between a first end of an incident bar and a first end of a transmitter bar. Next, a shock is induced proximate a second end of the incident bar. The shock may be induced by striking the second end with a striker bar or igniting an explosive proximate the second end of the incident bar. Next, the reflected and transmitted strain is measured as a function of time using at least one gauge disposed on each of the incident and transmitter bars. The dynamic shock loading response of the composite is measured using the measured reflected and transmitted strain. 3 figures
