Abstract
The Second World-Wide Failure Exercise is an international activity, organized by Hinton and Kaddour [The background to the Second World-Wide Failure Exercise (WWFE-II). 2012.], aiming at a better understanding of the limitations of existing failure criteria to predict failure under triaxial stressing. Part A of the exercise was to apply the failure criteria to the 12 test cases defined by the organizers of second world-wide failure exercise to predict strength. The presently reported Part B is to compare the predictions with the before unknown strength measurements, also provided by the organizers of second world-wide failure exercise. Hashin’s [Failure criteria for unidirectional fiber composites. J Appl Mech 1980; 47(6): 329–334.] model is used in its original form with one exception which is explained in the article. Problems with inhomogeneous stress distributions, arising in certain samples, are addressed. The deviations between predictions and measurements are quantified and explanations for those are given for the individual load cases.
