Abstract

Cracks in concrete structures often propagate under combined tensile (mode I) and shear (mode II) type of loading. Studies of mixed-mode failure are complicated by predictions of curved path, final crack location and crack instability. In the present paper, mixed-mode experiments were conducted using beams which have notches at different locations along the span of the beam. Depending on the geometries of specimens, the final crack may not occur at the location of the notch. Various crack initiation criteria were discussed and compared with the experimental results. Agreement between the experimental results and the theoretical predictions on the crack initiation angles, final failure locations and peak loads of the tested specimens was judged to be quite satisfactory.
