Sand Stone Young Modulus - spd-aachen-nord.de

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.

WHAT ARE THE VALUES OF MODULUS OF ELASTICITY & …

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.

Young's modulus - Wikipedia

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 ...

[PDF] Estimation of Static Young's Modulus for Sandstone ...

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.
