Abstract
We present a new version of the low frequency laboratory apparatus operating at seismic frequencies and at either confining or uniaxial pressures from 0 to 70 Mpa. The apparatus utilizes a stress-strain technique and measures the complex Young’s modulus, extensional attenuation and Poisson’s ratio of the rock sample at the range of strain amplitudes between 10-6 and 10-8.
