Dynamics Of Fracture

The dynamics of viscous compressible fluid in a fracture Jack Dvorkin*, Gary Mavko*, and Amos Nur* dynamic oscillatory fluid motion in large cracks is crucial in ABSTRACT detecting and evaluating natural and hydrofractures. We solve a problem of fluid dynamics in an arbitrar- Significant progress has been made in the quantitative

motion. This ubiquitous feature of fracture dynamics remains mysterious and suggests that essential elements may be missing from our understanding of the drying process. In this letter, we describe measurements of the dynamics of fracture in drying nanoparticle suspensions over seven decades in time. Over long time intervals, individual cracks ...
