Poisson’s Ratio is higher in Rubber, Steel or Wood?

Answer: When a material is compressed in one direction, it usually tends to expand in the other two directions perpendicular to the 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.
