Abstract
A finite-element analysis is carried out by using conforming quadrilateral elements in order to obtain the stress field near a rounded-tip V-notch in a beam under pure bending. Different values of the notch deptha, the radius of curvaturer at the notch root, and the angle ω between the opposite faces of the stress concentrator are considered under the assumption that the behavior of the material is either linear elastic or elastoplastic. Our results are compared with approximate solutions proposed by other authors.
