Abstract
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.
The Norris failure model was found to be very accurate in predicting multiaxial (biaxial and shear component) blunt notch strengths of Glare based on the Metal Volume Fraction approach. Moreover, a set of formulae is given to calculate the failure strength of an arbitrary laminate.
