Hysteresivity
Hysteresivity
Hysteresivity (pronounced: his-te-re-siv-i-ty) is a term used in the field of Biomechanics and Material Science to describe the energy loss that occurs in a system due to the hysteresis phenomenon.
Etymology
The term 'Hysteresivity' is derived from the word 'Hysteresis', which originates from the Greek word ὑστέρησις (hystéresis), meaning "deficiency" or "lagging behind". The suffix '-ivity' is added to denote a state or quality.
Definition
Hysteresivity is a measure of the energy dissipated in a material or system when it is subjected to cyclic loading and unloading. It is a dimensionless quantity and is calculated as the ratio of the area of the hysteresis loop to the total area under the loading curve.
