Young S Modulus Of Granite

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.

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. 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. G stress.

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. 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. Both granite and marble are natural stone.

Poisson s ratio varies between 0 2 and 0 3 for rocks. Granite is a type of common industrial natural stone. A half full bar means it s 50 of the highest and so on. Young s modulus or tensile modulus alt.

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.

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.

Shear modulus of elasticity or modulus of rigidity. The large ranges emphasize the need for testing at each site. Pressure is a force over an area so n m 2 or in si units kg m 1 s 2. Modulus of elasticity is a measure of stiffness of an elastic material.

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 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. High fracture densities up to 30 fractures m in this reservoir rock require that we. A full bar means this is the highest value in the relevant set.

Properties with values for just one material 1 in this case are not shown.
