Influence of Root Rotation on Delamination Fracture Toughness of Composites

Figure 6

Comparison of experimental [18] and fracture analysis results of the critical load and the corresponding displacement with the crack length of unidirectional DCB specimens made of carbon/PES composites ( = 20 mm, 2 = 4.05 mm, = 127 GPa, = 525 Nm, and = 2151 J/m²).
