Fracture Mechanics and Failure
Fracture Mechanics and FailureA major concern in the design of structural and machine components is the prevention of sudden catastrophic fracture. There are many documented cases in which the systems had functioned properly for many years, then suddenly broke. As experience increased, certain factors, such as low temperature and environment, appeared to exacerbate the problem. It was often found that the fracture originated from already existing cracks or surface (internal and external) discontinuities.An example of such behavior is usually found in fatigue fractures (see Sec. 2.13). If a component is loaded elastically below the yield strength, an…
