Proceedings of the 18th International Conference on Composite …, 2011•iccm-central.org… This study made an attempt to study mixed mode fracture behavior of foam core materials
by the aforementioned procedure with a custom made fixture using modified DCB
specimens tilted at various target values of inclination. Experimental data is collected by
recording intermittent crack growth on pre-cracked and prenotched samples for a given tilt
angle. … The modified DCB specimen with a V-shaped edge notch along the length of the
specimen provided a promising new approach to measure fracture behavior of pure foam …
