Enhanced fatigue endurance of metallic glasses through a staircase-like fracture mechanism.
Bulk-metallic glasses (BMGs) are now candidate materials for structural applications due to their exceptional strength and toughness. However, their fatigue resistance can be poor and inconsistent, severely limiting their potential as reliable structural materials. As fatigue limits are invariably governed by the local arrest of microscopically small cracks at microstructural features, the lack...
متن کاملEstimating Fatigue Curves With the Random Fatigue-Limit Model
In a fatigue-limit model, units tested below the fatigue limit (also known as the threshold stress) theoretically will never fail. This article uses a random fatigue-limit model to describe (a) the dependence of fatigue life on the stress level, (b) the variation in fatigue life, and (c) the unit-to-unit variation in the fatigue limit. We t the model to actual fatigue data sets by maximum likel...
متن کاملDoes Central Fatigue Limit Muscle Force Generation Capacity during Fatigue?
There is general agreement on peripheral factors of muscle fatigue that develop within the muscle and impair muscle fiber contractile mechanisms and muscle performance. Central factors of muscle fatigue that arise within the central nervous system have also been suggested to influence muscle force during fatigue. However, no direct empirical evidence of their influence on muscle force capacity ...
متن کاملLiterature review of race driver fatigue measurement in endurance motorsport
Driver fatigue in endurance motor racing, has been problematic for driver safety and optimal performance. Historically in this sport focus has been primary on improving mechanical performance; making the racecar light, faster and improving grip (aerodynamics and suspension geometry). Driver safety has come secondary. A series of fatal accidents that were attributed to fatigue have led to rule c...
متن کاملRelationships between muscle fatigue characteristics and markers of endurance performance.
The aim of this study was to examine the relationship of a range of in-vivo whole muscle characteristics to determinants of endurance performance. Eleven healthy males completed a cycle ergometer step test to exhaustion for the determination of the lactate threshold, gross mechanical efficiency, peak power and VO2max. On two separate occasions, contractile and fatigue characteristics of the qua...
