Influence of Root Rotation on Delamination Fracture Toughness of Composites

Figure 16

Comparison of experimental [27] and fracture analysis results of the critical load and the corresponding displacement with the crack length of DCB specimens made of carbon/epoxy (XAS-913C, Ciba Geigy plc) composites (lay-up: [0°]₂₄, = 20 mm, 2 = 3 mm, = 150 GPa, = 90.4 Nm, and = 297 J/m²).
