Blunt notch strength

This chapter describes the work performed to investigate the feasibility of using the Norris failure criterion for blunt notch strength prediction in Glare under arbitrary in-plane loading conditions (especially tension and shear). The described Norris method for Glare blunt notch is based on the experimentally determined blunt notch strengths in L-direction and LT-direction and the blunt notch strength under a 45° fibre off-axis angle.
