The different types of fatigue are described and safe life and fail-safe structures discussed. The methods used to design against fatigue are reviewed and the determination of the fatigue strength of components considered. A method for the prediction of the fatigue life of an aircraft is presented and crack propagation in structural components is ...

Probably the greatest proportion of failures of components or structures in service can be ascribed to failure by fatigue. This is a type of failure caused by the action of varying stresses below the short-term static tensile or torsional strength of the material.

Fatigue consists of the cycling loading of a structure over time, that is loading and unloading. Thus, the new aspect introduced is the unloading, which suppresses proportional loading at the crack tip and leads to the accumulation of residual stresses after unloading.

The Nature of Fatigue in Chronic Fatigue Syndrome
Qualitative Health Research, 2015In this article, we report the findings of our study on the nature of fatigue in patients diagnosed with chronic fatigue syndrome. Using ethnoscience as a design, we conducted a series of unstructured interviews and card sorts to learn more about how people with chronic fatigue syndrome describe fatigue. Participants ( N = 14) described three distinct

Fatigue is a common presenting complaint in primary care offices. Nearly everyone experiences fatigue at one time or another, typically caused by overexertion or lack of sleep. Fatigue in the athlete is problematic as it may affect training and competitive performance.

FATIGUE is one of the most interesting topics of conversation among physicians and nurses but, as is so true of many medical expressions, the exact meaning of the word "fatigue" is vague and indefinite. There are, of course, a great many ways of defining it.

What is Fatigue? Pathological and Nonpathological Fatigue
PM&R, 2010AbstractAid in understanding issues surrounding the construct validity of fatigue including the distinction between pathological versus nonpathological fatigue. Fatigue is a universal symptom reported by individuals in the general population as well as by those suffering from different medical and psychological illnesses, including cancer, multiple ...

Pilot fatigue is a significant, but often under-reported problem in both civilian and military aviation operations. Although estimates vary, official statistics indicate that fatigue is involved in at least 4-8% of aviation mishaps, and surveys of pilots and aircrew members reveal that fatigue is an important concern throughout today's 24/7 flight ...

Fatigue is a highly prevalent symptom in cancer patients. However in the daily practice this issue doesn't get adequate attention, because of limited therapeutic tools. A number of research issues in this field has been started during the last few years. Some of these new findings will soon modify and improve treatment options.
