Abstract:

Electromagnetic-gage type measurements were performed to determine fiber wire-matrix displacement during the compressive phase of shock loading. Fiber diameter and shock impedance were the variables investigated. The relative displacement was found to increase with the fiber diameter, but data for each fiber material could be well represented by a single curve if fiber diameter was used as the unit of relative displacement and shock transit time through the fiber diameter was used as the unit of time. Fibers attained the matrix velocity after a maximum, normalized relative displacement which varied linearly as the three-halves power of the shock impedance.
