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.

First of all kg cm 2 10 5 is not the correct unit for young s modulus which should be in units of pressure. Knowledge of the strength and elastic modulus of a reservoir rock is important for the optimisation of a particular geothermal resource. 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. Both granite and marble are natural stone.

Where e is the young s modulus and υis the poisson s ratio. Young s modulus or tensile modulus alt. The large ranges emphasize the need for testing at each site. 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. 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. Poisson s ratio varies between 0 2 and 0 3 for rocks. 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. There are 17 material properties with values for both materials. Properties with values for just one material 1 in this case are not shown. 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. 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. 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.

For each property being compared the top bar is granite and the bottom bar is marble. High fracture densities up to 30 fractures m in this reservoir rock require that we. Tensile modulus is often used for plastics and is expressed in terms 10 5 lb f in 2 or gpa. 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.
