Crack failure
WebA crack growth equation is used for calculating the size of a fatigue crack growing from cyclic loads. The growth of fatigue cracks can result in catastrophic failure, particularly in the case of aircraft. A crack growth equation can be used to ensure safety, both in the design phase and during operation, by predicting the size of cracks. WebFailure generally occurs due to complete fracture (brittle failure or excessive deformation), which may or may not result in rupture. In most cases, cracks are responsible for …
