Sand Stone Young Modulus. approximately 1 MPa and a Youngs Modulus of about 1 GPa. Triaxial tests conducted at confining pressures of less than 150 kPa yield an angle of internal friction of approximately 60 . Because the St. Peter sandstone disintegrates so readily when unconfined sampling the material is quite difficult.

13-02-2015· First of all, (kg/cm^2)*10^5 is not the correct unit for Young's modulus, which should be in units of pressure. Pressure is a force over an area, so N*m^-2 or in SI units kg*m^-1*s^-2. Maybe what you were going for was gigapascals, which would be (N/cm^2)*10^5, although a better way to write that would just be (N/m^2)*10^9.
where E is the effective Young's modulus of porous material with porosity p, E0 is Young's modulus of solid material, pc is a percolation threshold, i.e., the porosity at which the effective ...
Tensile Modulus - or Young's Modulus alt. Modulus of Elasticity - is a measure of stiffness of an elastic material. It is used to describe the elastic properties of objects like wires, rods or columns when they are stretched or compressed. Tensile Modulus is defined as the. "ratio of stress (force per unit area) along an axis to strain (ratio ...
Young's moduli are typically so large that they are expressed not in pascals but in gigapascals (GPa).. Although Young's modulus is named after the 19th-century British scientist Thomas Young, the concept was developed in 1727 by Leonhard Euler.The first experiments that used the concept of Young's modulus in its current form were performed by the Italian scientist Giordano Riccati in 1782 ...

In this study, we used artificial neural networks (ANN) to estimate static Young's modulus (E static ) for sandstone formation from conventional well logs. ANN design parameters were optimized using the self-adaptive differential evolution optimization algorithm. The ANN model was trained to predict E static from conventional well logs of the bulk density, compressional time, and shear time.

of sandstone and mudstone collected from Chongqing city, China. The results showed that both elastic modulus and uniaxial compressive strength of sandstone and mudstone were reduced by wetting and drying cycles, and that the degradation rate of the two mechanic parameters of mudstone was always larger than sandstone.

Dynamic Young's modulus, Ed = 35.44 GPa In general, the dynamic Young's and shear moduli are larger than their static values (there are however instances where the opposite is true). Eissa and Kazi (1988) studied the relation existing between the static modulus E (secant or tangent) and the dynamic modulus…
