What Is Elastic Modulus Of Granite

High fracture densities up to 30 fractures m in this reservoir rock require that we.

What is elastic modulus of granite. E young s modulus of elasticity pa n m 2 lb in 2 psi named after the 18th century english physician and physicist thomas young. Hooke s law of elasticity robert hooke 1635 1703 was a virtuoso scientist contributing to geology palaeontology biology as well as mechanics length extension e area force σ n e ε n where e is material constant the young s modulus units are force area n m2 or pa hooke s law σij cijklεkl. A half full bar means it s 50 of the highest and so on. Higher value of modulus of elasticity indicates good quality rock having sound composition.

4 modulus of rigidity granite 24 gpa shale 1 6 gpa limestone 24 gpa chalk 3 2 gpa sandstone 0 4 gpa steel 80 gpa wood 4 gpa glass 19 gpa lithostatic pressure gradient 26 46 mpa km for 2 70. Typical values of modulus of. A full bar means this is the highest value in the relevant set. This was achieved by using an ultraloading device to apply continuous and.

The large ranges emphasize the need for testing at each site. Granite is a type of common industrial natural stone. Properties with values for just one material 1 in this case are not shown. Knowledge of the strength and elastic modulus of a reservoir rock is important for the optimisation of a particular geothermal resource.

The reservoir rock for many geothermal projects in the upper rhine graben such as those at soultz sous forêts and rittershoffen both france is porphyritic granite. The graph bars on the material properties cards below compare granite to other natural stone materials top and the entire database bottom. For each property being compared the top bar is granite and the bottom bar is marble. Modulus of elasticity of rock modulus of elasticity of rocks depend upon several factors such as type of rock porosity grain size water content value of modulus of elasticity can be determined by static or dynamic methods.

Both granite and marble are natural stone. Elasticity is a property of an object or material indicating how it will restore it to its original shape after distortion. There are 17 material properties with values for both materials. Bulk modulus k granite 50 gpa shale 10 gpa limestone 65 gpa chalk 9 gpa sandstone 0 7 gpa.

We have analyzed the mechanical properties of granite under ultrasonic vibration and the characteristics of the damage produced. The new technique of using ultrasonic vibration to break hard rock is still in the experimental stage but it has significant potential for improving the efficiency of hard rock crushing. Elastic modulus is sometimes called young s modulus after thomas young who published the concept back in 1807.
