Abstract

Validation experiments to measure, quantify, and ultimately expand the fidelity of experimental data at a higher range of frequencies are presented. Previous efforts have identified distinct upper bandwidths on the order of 10 kHz (quantified by digital signal analysis techniques such as the signal coherence) in both explicit finite element simulations as well as experimental measurements. This limited bandwidth is insufficient for modeling the high-frequency (f > 50 kHz) response of impulsively-loaded structures, such as those undergoing impact. "Wideband" characterization of the structural dynamics is accomplished by considering the output characteristics of shock accelerometers and laser velocimeters. The results of these experiments are compared with previous efforts and compared with the current state-of-the-art.
