Influence of Root Rotation on Delamination Fracture Toughness of Composites

Figure 7

Comparison of experimental [19] and fracture analysis results of the critical load and the corresponding displacement with the crack length of unidirectional DCB specimens made of carbon/epoxy composites ( = 30 mm, 2 = 3 mm, = 37 Nm, = 150 GPa, and = 364 J/m²).
