Influence of Root Rotation on Delamination Fracture Toughness of Composites

Figure 5

Comparison of experimental [8] 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 ( = 25 mm, 2 = 4.18 mm, = 136 GPa, = 368 Nm, and = 263 J/m²).
