fatigue behavior of a vanadium microalloy steel has been studied in this research. here, microstructure constituents were considered which essentially are dependent on the heat treatment conditions. the results of high cycle fatigue tests revealed that heat treatment procedure and cooling rates have significant effects on fatigue properties. optimal heat treatment cycle of the microalloyed stee...

The deleterious consequences of fatigue have motivated decades of research to understand the impact of inadequate sleep on cognitive performance. A key objective is to use insights from that research to develop predictive models that can serve as valid tools for managing work-rest schedules and making Go, No-Go mission decisions. Ultimately, this is about maximizing human performance and minimi...
