Several important factors in bending fatigue life analysis of carburized components are discussed and included in the life prediction, such as bending stress gradient, mean stress, initial defect size, and residual stress.

Finally the pros and cons of the two fatigue life analysis approaches are compared and by: 6. small amount under the applied loading conditions, the deformation energy stored in the body will be changed.

The main application of engineered hydraulic fractures is the stimulation of oil and gas wells to increase production. Several physical processes affect the propagation of these fractures, including flow of viscous fluid, creation of solid surfaces and leak-off of fracturing fluid.

nuclear power plant piping, HDPE pipes with OD of mm (4 in.) to mm (36 in.) are most relevant, and were hence considered in the development of average empirical equations for SIF.
