✦ Synopsis

The calculation of stress intensity factor for a sharp V-notch is done from the limiting value of stress concentration factors as the root radius of the same V-notch rounded at the tip approaches zero. The stress analysis is carried out using the complex variable formulation of Muskhelishvili and the conformal mapping technique. The notch tip is rounded by a modified Schwartz-Christoffel transformation.

Ahstrati-Using the general formulas of stress concentration factor, methods for calculating stress intensity factor are mentioned. These methods make use of the several known values of stress concentration and radius of curvature at the point of stress concentration to form expression of stress conc
