youngs modulus diabase, Young's modulus, or the Young modulus, is a mechanical property that measures the stiffness of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear elasticity regime of a uniaxial deformation.Unconfined Compression Test | Geoengineer.org, The modulus of elasticity (Young's modulus) E which represents the ratio between axial stress and axial strain can be derived via several methods. Usually, it is calculated at stress-strain level of about 50% of the maximum load.Foundations, Modulus of Elasticity-(MPa x 1000) Limestone 3-27 Dolomite 7-15 Limestone (very hard) 70 Sandstone 10-20 Quartz-sandstone 60-120 Greywacke 10-14 Siltstone 3-14 Gneiss - fine 9-13 Gneiss - coarse 13-23 Schist - Micaceous 21 Schist - Biotite 40 10 14 2DETERMINED ELASTIC CONSTANTS OF ROCKS*, If Young's modulus, the cubic compressibility, Poisson's ratio and the density are E,, , o- and p, respectively, then it has been shown by the mathematical theory of elasticity that these six constants are related as follows: ...Some Useful Numbers, Some Useful Numbers on the Engineering Properties of Materials (Geologic and Otherwise) GEOL 615 Coefficient of sliding friction ( ) For most rocks, varies between 0.8 and 0.5. A value of 0.60 would be a good number for general use. Glass on glass 0.4.
Coarse Aggregate Properties, In a study by Aitcin and Mehta, they tested four different types of aggregates: diabase, limestone, gravel, and granite. Their test results showed that the limestone and diabase aggregates gave the highest values for the elastic modulus.
