The particular emphasis of this book is on new approaches to the notch effect problem in fatigue and fracture, and in particular the volumetric approach. These new methods are introduced in an attempt to replace the hot spot method, which suffers from some degree of empiricism. The work has given rise to a new field: notch fracture mechanics, in which a crack is considered as a particular case of a notch. Theoretical and practical aspects are presented in both fracture and fatigue. Special attention is paid to welded joints. This work is particularly recommended to engineers involved in safety design. Readers should possess adequate skill in strength of materials and fracture mechanics.

A vast majority of failures emanate from stress concentrators such as geometrical discontinuities. The role of stress concentration was first highlighted by Inglis (1912) who gives a stress concentration factor for an elliptical defect, and later by Neuber (1936). With the progress in computing, it is now possible to compute the real stress distribution at a notch tip. This distribution is not simple, but looks like pseudo-singularity as in principle the power dependence with distance remains. This distribution is governed by the notch stress intensity factor which is the basis of Notch Fracture Mechanics. Notch Fracture Mechanics is associated with the volumetric method which postulates that fracture requires a physical volume. Since fatigue also needs a physical process volume, Notch Fracture Mechanics can easily be extended to fatigue emanating from a stress concentration.
