Poisson S Ratio Of Granite

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.

Poisson s ratio of granite.

Balmer 29 zisman 30 and ramana and venkatanarayana 31 found that the static poisson s ratio is less than the dynamic poisson s ratio. Dr 0 334 100 10 3 m 5 10 3 m 10 m 1 7 10 5 m 0 017 mm. Typical poisson s ratios for some common materials are indicated below. Strength of materials engineering metals materials.

Poisson s ratios for common materials. Poisson s ratio of rock. It is a required computational input for the numerical stress analyses. Poisson s ratio varies between 0 1 for high strength concrete and 0 2 for weak mixes.

Poisson s ratio metals materials chart. Poisson s ratio in rock mechanics. For most rocks the value of poisson s ratio ranges in between 0 15 to 0 40. Poisson s ratio is a measure of the poisson effect that describes the expansion or contraction of a material in directions perpendicular to the direction of loading the value of poisson s ratio is the negative of the ratio of transverse strain to axial strain for small values of these changes is the amount of transversal expansion divided by the amount of axial compression.

It is normally taken as 0 15 for strength design and 0 2 for serviceability criteria. Poisson s ratio measures the ratio of lateral strain to axial strain at linearly elastic region. 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. 23 found no systematic trend in the difference between the.

Poisson s ratio is the ratio of lateral strain to longitudinal strain in a material subjected to loading. 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. The graph bars on the material properties cards below compare granite to other natural stone materials top and the entire database bottom.

A full bar means this is the highest value in the relevant set. The measurement of these properties is widely used in the evaluation of. Granite is a type of common industrial natural stone. 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.
