β¦ Synopsis
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 concentration factor. Values of stress concentration from handbooks or experiments and others can be used. This paper deals with plane elastic, longitudinal shearing and thin plate bending problem.

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 th
For the application of the weight function method the crack opening displacements for a reference case have to be known. An approximate method to derive the crack opening field from the stress intensity factor was proposed by Petroski and Achenbach [Engng Fracture Me&. 10,257 (1978)J. The limited ac
IT IS perhaps interesting to note that correction factors [(26/m) tan (m/2b)11'\* and [ ( see ao/2b)] In suggested by Irwin [ 1,2] and Feddersen [ 31, then discussed in Ref. (41 are trigonometricahy related. This may be illustrated by denoting x = no/U, squaring the correction factors (l/x) tanx <
The compounding methods for calculating stress-intensity factors for complex geometrical configurations are reexamined. It is shown that techniques which were developed specifically for problems involving localized loads, e.g. a pin-loaded hole with a crack at its edge, can also be used when the loa
