Poisson S Ratio Of Granite

23 found no systematic trend in the difference between the.

Poisson s ratio of granite. Poisson s ratio measures the ratio of lateral strain to axial strain at linearly elastic region. Poisson s ratio varies between 0 1 for high strength concrete and 0 2 for weak mixes. It is normally taken as 0 15 for strength design and 0 2 for serviceability criteria. 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 is the ratio of lateral strain to longitudinal strain in a material subjected to loading. The graph bars on the material properties cards below compare granite to other natural stone materials top and the entire database bottom. Strength of materials engineering metals materials. Granite is a type of common industrial natural stone.

Typical poisson s ratios for some common materials are indicated below. Poisson s ratio of rock. 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. For most common materials the poisson s ratio is in the range 0 0 5.

With poisson s ratio for aluminum 0 334 the contraction can be calculated as. 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. A half full bar means it s 50 of the highest and so on. Poisson s ratio in rock mechanics.

Poisson s ratios for common materials. Balmer 29 zisman 30 and ramana and venkatanarayana 31 found that the static poisson s ratio is less than the dynamic poisson s ratio. A full bar means this is the highest value in the relevant set. It is a required computational input for the numerical stress analyses.

Values of poisson s ratio for some common rocks. The measurement of these properties is widely used in the evaluation of. Dr 0 334 100 10 3 m 5 10 3 m 10 m 1 7 10 5 m 0 017 mm. The following is a chart of poisson s ratio for common engineering materials and metals.

Typical values of modulus of elasticity of some common are given in the table below.
