Abstract
An experiment was performed to determine the nature of the elastic stress system in the vicinity of an elliptical aperture in a plate subjected to uniform in-plane uniaxial tension, when the aperture is oblique to the plate midsurface. It was found that the maximum circumferential stress is somewhat higher than predicted by the Inglis solution for the “corresponding” plane problem. The possible relevance of these findings to elastic fracture mechanics is discussed.
