On Bridgman's stress solution for a tensile neck applied to axisymmetricalblunt notched tension bars

The displacement field at the minimum cross section of an axisymmetrical no tched tensile bar is analytically related to the notch root radius for larg e geometry changes of the notch profile, This,relationship is used to compl ete Bridgman's formula for the tensile load of a tensile necking in order t o predict the entire load-minimum diameter curve of an axisymmetrical blunt notched bar under tension. A particular case is solved by a finite element modeling to check the theoretical results derived at different stages of t he analysis.
