Young S Modulus Of Granite

Pressure is a force over an area so n m 2 or in si units kg m 1 s 2.

Young s modulus of granite.

Young s modulus or tensile modulus alt. Properties with values for just one material 1 in this case are not shown. Poisson s ratio varies between 0 2 and 0 3 for rocks.

Granite is a type of common industrial natural stone. Shear modulus of elasticity or modulus of rigidity. 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.

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. G stress. There are 17 material properties with values for both materials. 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.

The graph bars on the material properties cards below compare granite to other natural stone materials top and the entire database bottom. First of all kg cm 2 10 5 is not the correct unit for young s modulus which should be in units of pressure. 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. 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.

High fracture densities up to 30 fractures m in this reservoir rock require that we. Knowledge of the strength and elastic modulus of a reservoir rock is important for the optimisation of a particular geothermal resource. A full bar means this is the highest value in the relevant set. The large ranges emphasize the need for testing at each site.

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. Modulus of elasticity is a measure of stiffness of an elastic material. Elastic behaviour of an isotropic material can be characterized. Modulus of elasticity and ultimate tensile and yield strength for steel glass wood and other common materials sponsored links tensile modulus or young s modulus alt.

A half full bar means it s 50 of the highest and so on.
