KA* is the static bulk modulus of the empty rock (Toksoz, et al., 1976), but because of the lack of such data it is usually taken to be the dynamic bulk moduli of the dry rock.

The best known elastic constants are the bulk modulus of compressibility, Young's Modulus (elastic modulus), and Poisson's Ratio. The dynamic elastic constants can be derived with appropriate equations, using sonic log compressional and shear travel time along with density log data.

The compressive modulus of a material gives the ratio of the compressive stress applied to a material compared to the resulting compression, essentially how easy it is to squash the material between thumb and finger or in a vice. The compressive strength gives the stress that is needed to destroy the sample by crushing. There is a complication ...

eton of the formation) and bulk modulus of fluid, respectively. The Biot coefficient is defined as b= -1 k kd m/ a, where kd is the dry-rock bulk modulus. The Biot coefficient is only defined for the bulk modulus because it is the ratio of pore-volume change to total bulk-volume change under dry …

where, K sat is the saturated bulk modulus, K dry is the bulk modulus of dry rock frame, K m is the bulk modulus of the rock matrix, k fl is the bulk modulus of pore fluids and k m 2 is the porosity. Get Price And Support Online; An approximation for the Xu-White velocity model .

5.2 Method C, uniaxial compressive strength of rock is used in many design formulas and is sometimes used as an index property to select the appropriate excavation technique. Deformation and strength of rock are known to be functions of confining pressure. Method A, triaxial compression test, is commonly used to simulate the stress conditions under which most underground rock masses exist.

L 0 L A F E ∆ ∆ = This modulus reflects the stiffness of earth materials. E is the ratio of stress to strain.If our aim is to lengthen or shorten a rock without actually breaking it, the greater the value of E, the larger the stress that is needed to achieve the deformation.

• Average or secant bulk modulus is the slope of a line between any two points of the curve. That is: B s = (P 2 – P 1)V 0 /(V 1-V 2), or B s = ∆PV 0 /∆V. Because a line drawn between any two points appears as a chord of an arc, it is a secant, hence, the name secant bulk modulus.

Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate.

Table 3.4 gives average values of crushing strength of rocks, aggregate crushing value, abrasion value, impact value and attrition value for different rock groups. Modulus of Elasticity Modulus of elasticity of aggregate depends on its composition, texture and structure.

Proposed Moduli of Dry Rock and Their Application to ... - the USGS. known bulk moduli of the solid matrix, the frame, and the pore fluid and assumes that the shear modulus of sedimentary rocks is not affected by fluid saturation.

Below we plot the bulk density and P-wave impedance versus the gamma-ray values for a well in Colombia. The trends have the low-gamma-ray and the high-gamma-ray branches. This effect that is a result of the rock's microstructure results in non-uniqueness as the P-wave impedance is plotted versus the bulk density and porosity.
