Fatigue, a major still underestimated issue
Current Opinion in Oncology, 2018Purpose of review Cancer-related fatigue (CRF) is a frequent and distressing symptom present at any stage of the disease. However, it is still underreported, rarely properly assessed and undertreated. Recent findings There are international guidelines available, but also several ...

Fatigue damage analysis: Issues and challenges
International Journal of Fatigue, 2016Abstract During service loading of a vehicle (like an airplane), small cracks nucleate and eventually grow into large cracks, leading to structural damage that will threaten the safety of the vehicle. Managing safety is expensive. As a result, the goal is to provide a performance criteria that can be used as a tool by the designer to incorporate ...

Implantable electrical conductor flexure fatigue issues
Proceedings of 18th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2002Recent work calculating bending stresses in implantable conductors has been applied to cine-angiographic measurements of implanted conductor bending radii. The maximum stresses in different conductors due to flexure at the measured radii can be calculated. In evaluating the viability of this approach using the Universal Test Coil (UTC) described in the

Some issues in creep-fatigue research
Strength, Fracture and Complexity, 2021In the component operated at elevated temperatures, the life evaluation should be made in consideration of both creep and fatigue (creep-fatigue) such as the linear damage summation rule. However, the concept of creep-fatigue life evaluation has not spread well in the industry.

Assessment and epidemiologic issues related to fatigue
Cancer, 2001At The University of Texas M. D. Anderson Cancer Center, a multidisciplinary workgroup was assembled to review issues, current research, and areas of future research related to the assessment and epidemiology of cancer-related fatigue. Interactive discussion facilitated by a moderator determined the major areas of focus for future research in this ...

Central fatigue during exercise is the decrease in muscle force attributable to a decline in motoneuronal output. Several methods have been used to assess central fatigue; however, some are limited or not sensitive enough to detect failure in central drive. Central fatigue develops during many forms of exercise. A number of mechanisms may contribute to

Fatigue after Stroke: A Major but Neglected Issue
Cerebrovascular Diseases, 2001Subjective fatigue, defined as a feeling of early exhaustion developing during mental activity, with weariness, lack of energy and aversion to effort, remains virtually unstudied in patients with stroke, bur recent surveys suggest that it is a major, commonly overlooked, stroke sequela.

Fibromyalgia and Chronic Fatigue Syndrome: Management Issues
2015Fibromyalgia and chronic fatigue syndrome represent two of the most commonly encountered functional somatic syndromes in clinical practice. Both have been contentious diagnoses in the past, and this diagnostic dispute has resulted in a therapeutic nihilism that has been of great detriment to their management and to alleviation of the intense suffering ...

Critical issues in high cycle fatigue
International Journal of Fatigue, 1999High cycle fatigue (HCF) failures in materials used in rotating components of gas turbine engines have often been found to be attributable to fatigue loading on materials which have sustained damage from other sources. Damage can be present in the form of initial material or manufacturing defects, or can develop during service operation.
