Hey Ashish, Failure occurs due to the cyclic nature of load (below the load that would result in yielding), which causes microscopic flaws to grow into the microscopic crack. This crack can propagate to a critical size that leads to failure. Fatigue cracks usually initiate at stress concentrations,Read more
Hey Ashish,
Failure occurs due to the cyclic nature of load (below the load that would result in yielding), which causes microscopic flaws to grow into the microscopic crack. This crack can propagate to a critical size that leads to failure. Fatigue cracks usually initiate at stress concentrations, inclusions, weld defects Et cetera.
