The double-edge notched test, suggested by Reinhardt, to explore mixed mode fracture behav- iour is analysed. This paper presents detailed experimental data using this novel testing procedure. The tests were performed for three homotetic specimen sizes. Experimental crack trajectories are presented together with the corresponding load-displacement curves. Also, a numerical analysis of the tests was performed. The numerical model is based on the cohesive crack concept and extends it to shear fracture. Numerical results agree quite well with the experimental data. Other experimental set of shear loading fracture of double-edge notched specimens was modelled: the tests from Cedolin and co-workers.
