We have developed a workflow for computing the seismic-wave moduli dispersion and attenuation due to squirt flow in numerical model derived from micro X-ray computed tomography image of cracked (through thermal treatment) Carrara marble sample. To generate model, is processed, segmented, meshed. The finite-element method adopted solve linearized, quasistatic Navier-Stokes equations describing l...

[1] Understanding the mechanical behavior of rock is critical for researchers and decision-makers in fields from petroleum recovery to hazardous waste disposal. Traditional continuum-based numerical models are hampered by inadequate constitutive relationships governing fracture initiation and growth. To overcome limits associated with continuum models we employed a discrete model based on the f...
