...heat is a byproduct of hysteresis, not the other way around, because hysteresis is the "lagging" of stored energy behind its causing force.

...examples of hysteresis are: tires, transformers, magnetic recording, magnetic amplifiers.

...just about anything that deforms but doesn't exactly return to its pre-deformation characteristics, ie: less than 100% energy IN to energy OUT ratio...with some manner of intermediate energy "storage."
