The model was built using a large dataset of hysteresis loops—the stress-strain behaviors observed during repeated loading and unloading of the material—collected from low-cycle fatigue tests ...

My last column (“Designing with comparators,” EDN, March 29, 2001, pg 56) discussed basic comparator theory, and this column adds hysteresis to comparators to eliminate multiple switching on the ...

The hysteresis was calculated as the ratio of the area within the Fm-L loop to the area beneath the load portion of the curve. Conclusions: These results suggested that bed rest decreased the ...
