Abstract

In this paper, a method of evaluation of static strength by the application of mixed mode stress intensity factors of angular corner is considered. Recently, it has been found that the stress field near a corner of jointed dissimilar materials is expressed as a sum of the symmetric state with a singularity of 1/γ1-λ1 and the skew symmetric state with a stress singularity of 1/γ1-λ2. In this respect, the fracture tests are carried out on the plane specimens of acrylic resin having a single sharp notch. Different artificial notches are introduced into the specimens with varying the opening and inclination angles. The fracture criterion for different shaped notch is discussed on the basis of the stress distribution near the notch. The usefullness of K1, λ1 and K11, λ2 for the evaluation of static strength under mixed mode fracture is confirmed through the experiment.
