Abstract

Stress analysis of a single-edge-cracked specimen under uniaxial tension is performed by employing a Williams stress function and the boundary point collocation method. Full-field and singular stress fields are analyzed for small and large cracks, and it is shown that the inclusion of the nonsingular stresses in the description of the state of stress in the vicinity of the crack tip becomes significantly more important as the crack length decreases.
