Young S Modulus Of Granite

First of all kg cm 2 10 5 is not the correct unit for young s modulus which should be in units of pressure.

Young s modulus of 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. The graph bars on the material properties cards below compare granite to other natural stone materials top and the entire database bottom. Knowledge of the strength and elastic modulus of a reservoir rock is important for the optimisation of a particular geothermal resource. Young s modulus or tensile modulus alt.

Pressure is a force over an area so n m 2 or in si units kg m 1 s 2. High fracture densities up to 30 fractures m in this reservoir rock require that we. Properties with values for just one material 1 in this case are not shown. Both granite and marble are natural stone.

G stress. A half full bar means it s 50 of the highest and so on. Elastic behaviour of an isotropic material can be characterized. 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.

Poisson s ratio varies between 0 2 and 0 3 for rocks. 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. There are 17 material properties with values for both materials. Where e is the young s modulus and υis the poisson s ratio.

Shear modulus of elasticity or modulus of rigidity. Granite is a type of common industrial natural stone. 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. A full bar means this is the highest value in the relevant set.

Modulus of elasticity is a measure of stiffness of an elastic material. 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. The large ranges emphasize the need for testing at each site.

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.
