Young S Modulus Of Granite

Young s modulus or tensile modulus alt.

Young s modulus of granite.

E young s modulus n m 2 lb in 2 psi modulus of elasticity or young s modulus is commonly used for metals and metal alloys and expressed in terms 10 6 lb f in 2 n m 2 or pa. High fracture densities up to 30 fractures m in this reservoir rock require that we. A full bar means this is the highest value in the relevant set. Pressure is a force over an area so n m 2 or in si units kg m 1 s 2.

Knowledge of the strength and elastic modulus of a reservoir rock is important for the optimisation of a particular geothermal resource.

Modulus of elasticity is a measure of stiffness of an elastic material. Maybe what you were going for was gigapascals which would be n cm 2 10 5 although a better way to write that would just be n m 2 10 9.

For each property being compared the top bar is granite and the bottom bar is marble. Properties with values for just one material 1 in this case are not shown. Shear modulus of elasticity or modulus of rigidity. Poisson s ratio varies between 0 2 and 0 3 for rocks.

A principal stress component σ i produces a strain σ i e in the same direction and strains υ σ i e in orthogonal directions. Elastic behaviour of an isotropic material can be characterized. 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.

There are 17 material properties with values for both materials. Both granite and marble are natural stone. A half full bar means it s 50 of the highest and so on. Tensile modulus is often used for plastics and is expressed in terms 10 5 lb f in 2 or gpa.

Granite is a type of common industrial natural stone. The young s modulus or modulus of elasticity describes the limit for small strains of the rate of change of stress with strain a material is able to support. G stress. Where e is the young s modulus and υis the poisson s ratio.

Many natural stones have a modulus of elasticity of around 50 gpa which translates to 50 000 n mm 2 depending on the stone with pure quartz reaching a young s modulus of 71 7 gpa.
