International audienceMixed mode crack initiation in PMMA specimens containing square holes is investigated experimentally by uniaxial tensile tests. The crack deflection with respect to the V-notch bisector and the failure load both increase for decreasing hole sizes, to which correspond higher mode mixities. In order to catch this behavior from a theoretical point of view, Finite Fracture Mechanics (FFM) approach is employed numerically through a full finite element analysis. The FFM implementation requires only two material parameters, namely the strength and the fracture toughness. They are identified through the comparison between failure load predictions and experimental measurements on circular holes with different diameters. The res...
