A Calibration for a Modified Single Edge Notched Tension Specimen

CODEN: JTEVAB

Abstract

Using global and boundary collocation techniques, a single edge notched tension (SE(T)) specimen, modified by introduction of a semi-circular cutout in front of the crack, was developed and characterized. This specimen was found to produce fixed-grip K1 values two times greater than is possible with a conventional SE(T) specimen of the same size. This new specimen could be used to investigate upper transition crack arrest phenomena with smaller specimens and testing machine capacities than have been possible previously.
