Influence of Root Rotation on Delamination Fracture Toughness of Composites

Figure 13

Comparison of experimental [24] and fracture analysis results of the critical load and the corresponding displacement with the crack length of unidirectional DCB specimens made of carbon/PEK-C composites ( = 20 mm, 2 = 2 mm, = 48.2 GPa, , and = 863 J/m²).
