Fracture mechanics is a methodology that is used to predict and diagnose failure of a part with an existing crack or flaw. The presence of a crack in a part magnifies the stress in the vicinity of the crack and may result in failure prior to that predicted using traditional strength-of-materials methods. The traditional … See more Cracks act as stress risers and cause the stress in the part to spike near the tip of the crack. As a simple example, consider the case of an … See more There are three primary modes that define the orientation of a crack relative to the loading. A crack can be loaded in one mode exclusively, or … See more A material can resist applied stress intensity up to a certain critical value above which the crack will grow in an unstable manner and failure will occur.
