Single edge-crack stress intensity factor solutions

Weight function arguments and a boundary collocation technique are used to re-examine the stress intensity factor solutions to several classic two-dimensional linear elastic single edge-crack configurations. Limits to applicability and the solutions to the three and four-point bend, pure bending, eccentrically loaded tension, and other boundary condition problems are extracted from the solution to the uniformly loaded single edge-cracked configuration. A simple representation of the asymptotic behavior is proposed and a common expression that captures the full range of crack length to specimen width ratio is presented.
