The Hugoniot elastic limits (HEL) of a high-density aluminum oxide ceramic (Lucalox) and a slightly lower-density ceramic (porosity approximately 4%) were determined to be 112±13 and 83±5 kbar, respectively. Above the HEL, the shock-stress-volume Hugoniot curves for both materials are offset by 40 kbar or more above their hydrostatic-pressure-volume curves. These results indicate that shear stresses with magnitudes of about 30–40 kbar persist in aluminum oxide to shock-pressure levels of at least 300 kbar.

Additional Information:©1968 The American Institute of Physics (Received 16 February 1968; revised 24 May 1968) The work carried out at Lawrence Radiation Laboratory was performed under the auspices of the U.S. Atomic Energy Commission. The work at Stanford Research Institute was in part supported by the Army Materials Research Agency. The in clined-mirror experiments were carried out with the assistance of M.J. D'Addario, C.A. Falco, J.W. Schimmel, and W.C. Mumper at LRL. The flash-gap experiments were performed by B.L. Hord. The program at SRI was initiated by A.F. Florence and experiments were carried out by J.T. Rosenberg. Calculations of the temperature and of the isotropic compression curve from ultrasonic data were independently performed by Richard Grover. Our understanding of the failure mode in ceramics has been greatly improved by conversations with Albert C. Holt.
