Young S Modulus Of Granite

Granite is a type of common industrial natural stone.

Young s modulus of granite.

G stress. The large ranges emphasize the need for testing at each site. Modulus of elasticity is a measure of stiffness of an elastic material. Young s modulus or tensile modulus alt.

Both granite and marble are natural stone. For each property being compared the top bar is granite and the bottom bar is marble. A full bar means this is the highest value in the relevant set. 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. 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. Tensile modulus is often used for plastics and is expressed in terms 10 5 lb f in 2 or gpa.

Properties with values for just one material 1 in this case are not shown. High fracture densities up to 30 fractures m in this reservoir rock require that we.

There are 17 material properties with values for both materials.

Knowledge of the strength and elastic modulus of a reservoir rock is important for the optimisation of a particular geothermal resource. First of all kg cm 2 10 5 is not the correct unit for young s modulus which should be in units of pressure. Shear modulus of elasticity or modulus of rigidity. The graph bars on the material properties cards below compare granite to other natural stone materials top and the entire database bottom.

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

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.
