The elasticity of a material is generally evaluated in two ways:
1. Elastic Modulus (Young Modulus): It is a parameter that measures how much deformation the material undergoes when tension or pressure is applied. A high elastic modulus means the material is harder and less susceptible to deformation.
2. Poisson's Ratio: It refers to the rate at which extension or compression of the material along one axis results in expansion or contraction along the other axis. An elastic material is generally one with a low Poisson's ratio.
The high elasticity of a raw material means that deformations are minimal and the material can quickly return to its original form, especially when under tension or pressure. These properties can be important for many applications in which a material is used, such as in tires or springs.
