Modulus of elasticity rock
Web31 dec. 2010 · The modulus of elasticity values obtained will usually be less than moduli derived under rapid load application (dynamic or seismic rates, for example), and will usually be greater than values under slow load application or extended load duration, given other test conditions being the same. Scope Web11 sep. 2024 · Elastic Moduli The following definitions assume a linearly elastic, homogenous isotropic material. Young's Modulus Young's modulus, E (Pa), describes a material's ability to stretch or compress by quantifying how resistant a material is to extensional deformation.

Web6 feb. 2024 · The Young's modulus quantifies the ability of an object to resist deformation through the elastic strength arising from the crystal structure of the rock. Typical values for Young's modulus are in the range of 10 MPa to 70 GPa (see Table \PageIndex {1}\)
Web12 apr. 2024 · This meant that the 16-ply samples were seen to have a more significant decrease in elastic moduli, especially the elastic modulus in tension. However, the samples tested in this research were cut to be 180 × 180 mm 2 , which does not meet the drop weight testing standard that suggests a size of 100 × 150 mm 2 . Web10 mrt. 2012 · The modulus of elasticity of intact rock is one of the most important rock properties used in designing civil construction projects such as dams and tunnels and designing mine layouts. High-quality core samples are needed to obtain this parameter in laboratory tests.
