Compression wave studies in Oakhall limestone

PDF Version Also Available for Download.

Description

A series of 15 large amplitude (0-4.0 GPa) compression wave experiments have been performed on Oakhall limestone using impact techniques. Time-resolved particle velocity profiles were determined with window laser interferometry. Three experiments were performed at each impact velocity on samples of different thickness and stress-strain behavior was determined through Lagrangian analysis of the measured wave profiles. Two shock-induced phase transformations are observed within the range of the data. The first occurs within the elastic region of response and initiates a rarefaction shock wave on unloading. The second is characteristic of the more sluggish transformations observed in silicate rock. The present ... continued below

The second is characteristic of the more sluggish transformations observed in silicate rock. The present data have been used to demonstrate the importance of shear in shock-induced phase transformations.
