Abstract
An experimental investigation was conducted to study the behavior under biaxial tensile loading of quasi-isotropic graphite/epoxy plates with circular holes and to determine the influence of hole diameter on failure. Maximum strains at failure on the hole boundary reach values up to twice the ultimate strain of the unnotched laminate. The effect of hole diameter on strength was described satisfactorily using an average biaxial stress criterion. Good correlation was also obtained with theoretical predictions based on a tensor polynomial failure criterion for the lamina and a progressive degradation model.
