This paper is about finite element calculations of the Mode stress intensity factor K1, and the T-stress T, for single edge-notched tension SENT specimens. Linear elastic fracture mechanics LEFM is used. Four cases of traction application method and plane state TAMPS are considered, applied uniform load and plane stress LS applied uniform load and plane strain LN, applied uniform displacement and plane stress OS, applied uniform displacement and plane strain DN. For all cases, the material is considered to be incompressible, i.e., 0.5 is used for Poissons ratiov.
