Fatiguecritical
Fatigue-critical is a designation used in engineering to describe a component, region, or system whose failure due to cyclic loading would significantly affect safety, operability, or reliability. Elements deemed fatigue-critical are singled out for heightened attention in design reviews, maintenance planning, and safety assessments because fatigue life is a dominant reliability constraint.
Factors that render a part fatigue-critical include repeated or fluctuating stresses, high stress concentrations such as
Assessment typically involves identifying potential fatigue hotspots through structural analysis, material data, and service load histories.
Mitigation strategies aim to extend fatigue life or reduce the likelihood of catastrophic failure. These include
Applications are common in aerospace, automotive, wind energy, civil infrastructure, and any safety-critical system where cyclic
