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 s

The effect of a side-groove constraint on a pre-cracked Charpy-size specimen, and the influence of a side-groove on fracture tou&ess parameters are studied. The results indicate that when side-groove depth approaches a critical value, the maximum load toughness & values are nearly coincident with th
Finite element simulations of the three point bend fracture toughness specimen have been performed to investigate the effect of crack front curvature and side-grooving. Even modest crack front curvature moves the position of maximum energy release rate from the center towards the free surfaces of th
