What is Effect of Side Grooves on the Elastic-plastic Stress State of Fracture Toughness Specimens—three-dimensional Finite Element Analysis about?

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 middie region. Accordingly, differences of the plastic zone size and the stress through the thickness increase with increasing the load. Although the side groove promotes the severe plastic deformation over limited region near the root of the groove, practically even distributions of the plastic zone and the dilatant stress can be resulted on V-grooved and slitted specimens.
