✦ Synopsis

Two sets of stress intensity factor solutions to the "benchmark" surface flaw problems are compared: one set of results calculated from the Barsoum extrapolation equation and the other derived from a modified linear extrapolation equation suggested by the authors. Magnification factors for a semi-elliptical crack subjected to remote tension and bending are employed in both methods for comparison. Both checks indicate good agreement with the results of the modified linear extrapolation equation. Results extrapolated from the Barsoum equation differ significantly from the 'best estimate curve" for the remote bending case..

## Abstract For calculating stress concentration factors at plane notches and stress intensity factors at plane cracks a system of finite elements is proposed which uses specially developed triangular hybrid stress elements at the notches and cracks and combines them with triangular elements acordi
