Abstract
The stress and strain fields were determined in the neighbourhood of a sharp notch in a single edge-notched tensile specimen. The effects of notch opening, distance from the notch and unloading the specimen and the difference between plane stress and plane strain were investigated. From the measurements of the strain field, the stress was inferred directly from the stress-strain curve of the material. In general, the stress field is fairly uniform between the notch and the craze tip, in good conformity with the assumption of the Dugdale theory. Complexities in the strain field arise from the stress concentration at the corners of the bottom of the notch and from the characteristics of the craze.
