Bulk modulus for fluid saturated rocks at intermediate

SUMMARY. Squirt flow is an essential cause of wave dispersion and attenuation in saturated rocks. The squirt flow model, proposed by Gurevich et al., has been widely applied to explain the wave dispersion and associated attenuation for saturated rocks at sonic and seismic frequency bands.In this model, the saturated bulk modulus is obtained by taking the partially relaxed frame bulk modulus as ...

As a result of the induced pore collapse and grain crushing, Young’s modulus at the effective pressure P eff = 5 MPa dropped from ~ 12 GPa for the intact sample to ~ 6 GPa for the compacted sample.

Bulk modulus Wikipedia

The bulk modulus (or ) of a substance is a measure of how resistant to compression that substance is.list of stone crusher manufacturer in uae.It is defined as the ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume. Other moduli describe the material's response to other kinds of stress: the shear modulus describes the response to shear stress, and Young's modulus describes the response to ...

Brittle strength of basaltic rock masses with applications

Jun 25, 1993 Temperatures comparable to those at the Venus surface may slightly increase the deformation modulus but decrease the compressive strength of the rock mass. Brittle strength envelopes for the rock mass as a function of depth are typically stronger in both extension and compression than conventional envelopes that assume a simple frictional strength.uaen crusher for sale Fote Mining Machinery Co.

rock Mechanical properties Britannica

rock - rock - Mechanical properties: When a stress σ (force per unit area) is applied to a material such as rock, the material experiences a change in dimension, volume, or shape. This change, or deformation, is called strain (ε).jaw-type crushing machine, Fote. Stresses can be axial—e.g., directional tension or simple compression—or shear (tangential), or all-sided (e.g., hydrostatic compression).

Sep 03, 2021 The initial modulus of the collapsed rock mass decreases exponentially with the increase in the crushing expansion coefficient but decreases gently with the uniaxial compressive strength decreasing. The initial modulus of the collapsed rock mass decreases greatly when the crushing expansion coefficient is less than 1.6; conversely, it decreases ..Fote Mining Machinery Co..

Effects of pore collapse and grain crushing on ultrasonic

Aug 21, 2007 The parameter δ characterizes the coupling between the solid stress and the fluid pressure, and thus determines the fluid impact on the effective crack compliance: δ compares the fluid bulk modulus Kf to what is an apparent crack bulk modulus (1 − νo /2) Eoζh, where ζ is the crack aspect ratio, which is the ratio between the aperture to the diameter.
