Hysteresis and elasticity are two key properties of materials that are closely related to each other. Elasticity is the ability of a material to deform under stress and return to its original shape once the stress is removed. Hysteresis, on the other hand, is the energy lost during the deformation and recovery process.

In materials with high elasticity, such as rubber or some types of plastics, the deformation under stress is reversible and the material returns to its original shape with minimal energy loss. But, materials with low elasticity, such as metals, have a more permanent deformation under stress and a higher energy loss during the recovery process.

Hysteresis affects the elasticity of a material by reducing its ability to store and recover energy. The energy lost during the deformation and recovery process can decrease the material’s elasticity over time. This effect is particularly pronounced in materials that undergo cyclic loading, where the energy loss accumulates with each cycle.

NextGen’s Digitest II is the industry leading Shore and IRHD hardness tester capable of doing Hysteresis and will be very useful for rubber manufacturers.
