Read More1/1/2017· Keywords: "rock mechanics, Young's modulus; laboratory rock tests; range of elasticity" The elastic behaviour of rocks and the range of their elasticity are of crucial importance in rock engineering. In solving problems in mining engineering or tunnelling, the change of stress fields forced by an excavation drivage first depends on the elastic
Read MoreThe elasticity is an important parameter for the evaluation of the mechanical behavior of a rock mass and a fundamental factor in the definition of the resistance characteristics, stability, and blastability in rock blasts, and it is an important parameter for the blastability equations like the Kuz–Ram method.
Read Morefor all ﬂuids for frequencies below 20 Hz but underpredicts the water-saturated basalt bulk modulus for frequencies greater than 20 Hz. The most likely reason is that the pore-ﬂuid pressures are unrelaxed. Instead, the ultrasonic frequency rock moduli are modeled with high-frequency elastic theories of squirt ﬂow and Kuster–Toksöz (KT).
Read MoreThe basalt fibers typically have a filament diameter of between 10 and 20 μm which is far enough above the respiratory limit of 5 μm to make basalt fiber a suitable replacement for asbestos. They also have a high elastic modulus, resulting in high specific strength —three times that of steel.
Read MoreTable of Modulus of Elasticity of Rock. Figure Load/deflection paths for an arch dam. For example, as the reservoir behind the arch dam rises, the rock under the arch responds along curve 1. The concave upward curvature of this load/deflection path is typical for fractured rocks on first loading because the fractures close and stiffen at low loads.
