Fatigue is a major human factors issue in aviation safety. [1] The Fatigue Avoidance Scheduling Tool ( FAST) was developed by the United States Air Force in 2000–2001 to address the problem of aircrew fatigue in aircrew flight scheduling. [2] FAST is a Windows program that allows scientists, planners and schedulers to quantify the effects of ...
Fatigue testing is a specialised form of mechanical testing that is performed by applying cyclic loading to a coupon or structure. These tests are used either to generate fatigue life and crack growth data, identify critical locations or demonstrate the safety of a structure that may be susceptible to fatigue.
The Patient-Reported Outcomes Measurement Information System [1] ( PROMIS) provides clinicians and researchers access to reliable, valid, and flexible measures of health status that assess physical, mental, and social well–being from the patient perspective. PROMIS measures are standardized, allowing for assessment of many patient-reported ...
Fatigue (material) Fracture surface of an aluminium crank arm from a bicycle. The dark area (due to oil, dirt and fretting) is a slow growth fatigue crack and may contain striations. The bright area is caused by sudden fracture. Mechanical failure modes. Buckling.
Mental fatigue is a temporary inability to maintain optimal cognitive performance. The onset of mental fatigue during any cognitive activity is gradual, and depends upon an individual's cognitive ability, and also upon other factors, such as sleep deprivation and overall health. Mental fatigue has also been shown to decrease physical ...
Thermo-mechanical fatigue. (Redirected from Thermo-Mechanical Fatigue) Thermo-mechanical fatigue (short TMF) is the overlay of a cyclical mechanical loading, that leads to fatigue of a material, with a cyclical thermal loading. Thermo-mechanical fatigue is an important point that needs to be considered, when constructing turbine engines or gas ...
Compassion fatigue is an evolving concept in the field of traumatology. The term has been used interchangeably with secondary traumatic stress ( STS ), [1] which is sometimes simply described as the negative cost of caring. [1] Secondary traumatic stress is the term commonly employed in academic literature, [2] although recent assessments have ...
Implementation of fatigue prediction models, such as the Sleep, Activity, Fatigue, and Task Effectiveness model, optimize scheduling by being able to predict pilot fatigue at any point in time. Although the mathematical model is limited by individual pilot differences it is the most accurate existing prediction because it takes into account ...
