- Abstract
- A failure criterion must be considered for each failure mode and parameters of the model determined in each case. In this study, a failure criterion was developed by introducing the notion of equivalent biaxial strength under biaxial loading of tension and torsion. The experimental results showed that the equivalent biaxial strength has a power-type relation to a parameter, cos psi. The failure strength under biaxial loading can be predicted as a function of tensile strength, torsional strength and biaxial ratio. Scattering of the experimental data can be predicted using a Weibull distribution function and the concept of equivalent biaxial strength. The model should accurately predict the biaxial strength of general laminated composite materials. (C) 1999 Published by Elsevier Science S.A. All rights reserved.
