Poisson ratio of rigid body is 0/0
indeterminate

µ for a rigid body can not be determined as no change in lateral as well as longitudinal strain, µ = 0/0

as our point of view poison ratio ranges -ve to +ve value. the material which have +ve value lateral dimension contract as force applied in longitudinal direction. the material which have -ve value lateral dimension expand too same as longitudinal direction. in between a state where poison ratio is 0 lateral dimension remains unchanged even a increment in longitudinal direction take place.

Rigid body means it cannot changes its dimension even application of force therefore it is ideal body..so when load is applied its linear strain and lateral strain is zero.. so ratio of 0÷0 is infinity..therefore we cannot calculate value of poissions ratio. So it is not zero.

- Poisson's ratio: The ratio of lateral strain to linear strain is constant, when homogeneous material is loaded within elastic limit.

- Poisson's ratio is denoted by μ or 1/m (Value of m is between 3 and 4).

- The value of Poisson's ratio is equal to zero for a rigid body. Concrete has the value of Poisson's ratio between 0.25 and 0.34.

- Lateral strain is inversely proportional to linear strain. As lateral strain decreases longitudinal strain increases.

- Stable, isotropic, linear elastic materials have Poisson's ratio between – 1.0 and 0.5, because Young's modulus, shear modulus and bulk modulus have positive values.
