Abstract Elastic-plastic stress states on double-edge-notched tensile specimens are analyzed by the three-dimensional finite element method. Effect of side grooves on the stress state around the crack tip are discussed on specimens about 30% side-grooved in U , V and slit types comparing with a regular flat specimen. On the flat specimen, the plastic zone develops extensively near the free surface but the dilatant stress there does not increase so much as at middle region. Accordingly… CONTINUE READING
