Dispersion effect of velocities on the evaluation of material elasticity

Journal of Mining Science (Impact Factor: 0.4). 07/2009; 45(4):347-354. DOI: 10.1007/s10913-009-0043-4

ABSTRACT The author employs the Kjartansson absorption model to prove that intrinsic dispersion of seismic wave velocities in absorbing
media is a basic factor responsible for the differences between elastic rock parameters measured dynamically and statically.
Dispersion of Young’s modulus predicted by this model for a frequency range from millihertz to tens of kilohertz matches well
the experimental data obtained for polyvinyl chloride plastic used as a test material in the study case.

    ABSTRACT: Static and dynamic bulk moduli (K/sub s/ and K/sub d/) are measured as continuous functions of pressure from zero to 2--3 kilobars for two sandstones, a tuff, limestone, granite, and oil shale. Results for the sandstones and granite are in good agreement with previously reported data with K/sub s//K/sub d/ varying from about 0.5 at atmospheric pressure to close to unity at pressures 2 kilobars and above. For rocks behaving elastically under static loading, the K/sub s//K/sub d/ ratio is inversely related to the microcrack density. For the limestone, time dependent deformation associated with pore collapse results in K/sub s//K/sub d/ ratios approaching 0.1 at high pressure. Upon unloading, while initially high (approx.1.0) at high pressures, K/sub s//K/sub d/ becomes lower than values obtained during loading at low pressures (
