Young S Modulus Of Granite

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.

Young s modulus of granite.

Both granite and marble are natural stone. Pressure is a force over an area so n m 2 or in si units kg m 1 s 2. Granite is a type of common industrial natural stone. Where e is the young s modulus and υis the poisson s ratio.

For each property being compared the top bar is granite and the bottom bar is marble. 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. There are 17 material properties with values for both materials. 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.

Shear modulus of elasticity or modulus of rigidity. 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. Poisson s ratio varies between 0 2 and 0 3 for rocks. First of all kg cm 2 10 5 is not the correct unit for young s modulus which should be in units of pressure.

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. G stress. Elastic behaviour of an isotropic material can be characterized. 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. The large ranges emphasize the need for testing at each site. The graph bars on the material properties cards below compare granite to other natural stone materials top and the entire database bottom. Tensile modulus is often used for plastics and is expressed in terms 10 5 lb f in 2 or gpa.

Young s modulus or tensile modulus alt. A full bar means this is the highest value in the relevant set. 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. Properties with values for just one material 1 in this case are not shown.

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