Influence of Root Rotation on Delamination Fracture Toughness of Composites
Figure 10
Comparison of experimental [22] and fracture analysis results of the critical load and the corresponding displacement with the crack length of unidirectional DCB specimens made of carbon/epoxy (T300/634DDS) composites ( = 2.5 mm, 2 = 12.5 mm, = 133 GPa, , and = 642 J/m2).
