✦ Synopsis

The pressure dependence of the elastic constants of various halides, hard tissues and synthetic apatites have been examined in the 0-to 50-kilobar range using a solid media, pressure apparatus coupled with an ultrasonic interferometer. The samples include : hydroxy-, fluor-, and chlor-apatite, NaC1, CaF2, mollusc shell (aragonite), ivory, dentin and enamel, and fish, bovine, and human bones. High pressures were used in order to assess the effects of porosity in aggregate samples and to make measurements on specimens of ideal density. Computer analysis of the measured longitudinal and shear ultrasonic velocit,ies yields the pressure dependence of the bulk, shear, and Young's moduli and Poisson's ratio. Atmospheric pressure values at ideal density are obtained by back extrapolation from the high pressure measurements.
