The basic concepts of elastic and inelastic behavior are presented. The elevation of stresses at notches. the stress concentration factor and fatigue notch factor and sources of differences between these factors are introduced. Inelastic stress-strain response at a notch, Neuber's rule, residual stresses subsequent to notch yielding, and reduction of stress concentrations are discussed.
