Hysteresis represents the energy loss during the loading and unloading periods and is defined as the difference between the strain energy required to generate given stress in the sample and the elastic energy at that stress. The hysteresis loss ratio is defined by the hysteresis loop area (yellow area) divided by the energy loading area (dotted area).
