Why Poisson Ratio Is Higher In, Rubber/steel/wood?

Answer»

When a material is COMPRESSED in one DIRECTION, it usuallytends to EXPAND in the other two DIRECTIONS perpendicular tothe direction of compression. This phenomenon is CALLED the Poisson effect. Poisson’s ratio is a measure of the Poisson effect.

For rubber = 0.5
For steel = 0.288
For wood < 0.2

Thus Poisson’s ratio is higher in RUBBER.
