WebStatic moduli derived from the slope of a stress-strain curve and dynamic moduli derived from the velocity of elastic waves are significantly different for rocks, even though they should be equal according to the theory of linear elasticity. Proper knowledge about this difference might be useful because dynamic measurements are often the only … Web13 apr. 2024 · Natural rocks usually are obviously heterogeneous, such as granite, gneiss and amygdaloidal basalt. Grain-scale heterogeneity of rocks is a combination of several types of heterogeneity, including geometric heterogeneity resulting from grain shape; material heterogeneity resulting from the mismatch of different grains; and contact …
How to Calculate Elastic Modulus Sciencing
Webrepresents the elastic rock response. Using AE (acoustic emission) devices, it has been found that starting at point B microcracks develop in the rock sample and the sample … Web15 sep. 2024 · The results show that the elastic modulus and hardness of the quartz in the granite is the largest, the feldspar is the second, the mica is the smallest. The main mineral contents in granite were analyzed using the semiquantitative method by XRD and the rock slice identification test. indice bt43 2023
