The elasticity of collagen improves fracture resistance. PAN has properties involving low density, thermal stability, high strength and modulus of elasticity. This is known as elastic deformation or elasticity. Examples are material constants such as modulus of elasticity and specific heat. Scar tissue also lacks elasticity unlike normal tissue which distributes fiber elasticity. Young's modulus quantifies the elasticity of the polymer. The modulus of elasticity may often be considered constant. A Maxwell material is a viscoelastic material having the properties both of elasticity and viscosity. The material has superior elasticity and absorption. This incorporates both the elasticity and viscosity of the material. It had all the desired properties of elasticity and strength. In general usage "elasticity" refers to flexibility. The size depends on the elasticity of demand curve. Temperature effects are also present in the demonstrated elasticity of a polymer. "C" is inversely proportional to the mechanical elasticity of the sensor.
