...-sectional area, the true stress σ will not be equal in tension and in compression because of cross-sectional area effects. When tension force is applied, the cross-sectional area is reduced according to Poisson’s ratio, increasing the true tensile stress σ t over its nominal engineering value S t...

... (such as machining marks, surface flaws, notches, etc.) cause stress concentration. Material heterogeneities (such as inclusions, second-phase particles, voids, microcracks) also can act as stress concentrators. These areas of stress concentration permit local permanent plastic deformation at nominal stresses below...

Compressive mean stresses (in the form of residual stresses) are frequently introduced intentionally to fatigue-prone areas of a component so as to prolong fatigue life. Unfortunately, the benefit may not be fully realized if the local cyclic strain...
