[PDF][PDF] Acoustic velocity and attenuation in porous rocks

KW Winkler, WF Murphy III - Rock physics and phase relations. A …, 1995 - Citeseer
The acoustic properties of most crustal rocks are dominated by microcracks, pores, and the
fluids contained within them. Dry rocks have much lower elastic moduli than do any of the …

Damage monitoring in rock specimens with pre-existing flaws by non-linear ultrasonic waves and digital image correlation
