Dislocation Configurations Due to Plate Impact

  • Conference paper

Summary

Plate impact recovery experiments are described in which single crystals of LiF are impacted by a thin flyer plate. Provisions are made to prevent reloading of the crystal by reflected waves or repeated impact. As a result, the crystal remains in position for subsequent removal to examine the dislocation configurations produced by a known stress pulse. Observation of dislocations by an etch pit technique shows large increases in dislocation density with closely spaced, long glide bands emanating from both front and rear surfaces. Comparatively short, widely spaced interior glide bands have lengths comparable to those predicted by applying the linear drag model of ultrasonic attenuation studies to the stress levels of the plate impact experiments.
