Poisson S Ratio Of Granite

A full bar means this is the highest value in the relevant set.

Poisson s ratio of granite.

Poisson s ratio in rock mechanics. Since poisson s ratio is a mechanical property that plays a role in the deformation of elastic materials it is utilized in rock engineering problems associated with the deformation of rocks e g. It is normally taken as 0 15 for strength design and 0 2 for serviceability criteria. Values of poisson s ratio for some common rocks.

The measurement of these properties is widely used in the evaluation of. Typical poisson s ratios for some common materials are indicated below. The graph bars on the material properties cards below compare granite to other natural stone materials top and the entire database bottom. The following is a chart of poisson s ratio for common engineering materials and metals.

Poisson s ratio measures the ratio of lateral strain to axial strain at linearly elastic region. However sutherland 32 and vanheerden 26 found that the static poisson s ratio is greater than the dynamic poisson s ratio whereas tutuncu et al. A half full bar means it s 50 of the highest and so on. It is a required computational input for the numerical stress analyses.

The elastic moduli young s modulus shear modulus and poisson s ratio and damping of concretes and refractories materials can be accurately characterized with the sonelastic systems of non destructive testing both at room temperature as for low and high temperatures. With poisson s ratio for aluminum 0 334 the contraction can be calculated as. For most rocks the value of poisson s ratio ranges in between 0 15 to 0 40. 23 found no systematic trend in the difference between the.

Poisson s ratio of rock. Granite is a type of common industrial natural stone. Balmer 29 zisman 30 and ramana and venkatanarayana 31 found that the static poisson s ratio is less than the dynamic poisson s ratio. Typical values of modulus of elasticity of some common are given in the table below.

For most common materials the poisson s ratio is in the range 0 0 5. Poisson s ratio varies between 0 1 for high strength concrete and 0 2 for weak mixes. Dr 0 334 100 10 3 m 5 10 3 m 10 m 1 7 10 5 m 0 017 mm. Poisson s ratios for common materials.
