The fatigue limit or endurance limit is the stress level below which an infinite number of loading cycles can be applied to a material without causing fatigue failure. Some metals such as ferrous alloys and titanium alloys have a distinct limit, whereas others such as aluminium and copper do not and will eventually fail even from small stress amplitudes. Where materials do not have a distinct limi… Web6 hours ago · Physical and mental fatigue severity were categorised by Likert and Bimodal score respectively as ‘normal’ (Likert 0–9, bimodal 0‒3), ‘mild’ (10–15, and 4–7), or moderate to severe (≥16, and ≥8).
