Generation and Validation of Crack Growth Resistance Curve from DCB Specimens: An Experimental Study

This article examines fracture toughness and interlaminar failure load of double cantilever beam (DCB) specimens made of glass/epoxy of three different lay-ups. The present model requires the applied load–displacement history and crack extension to generate the crack growth resistance curve ( R -cur...

Zusammenfassung:This article examines fracture toughness and interlaminar failure load of double cantilever beam (DCB) specimens made of glass/epoxy of three different lay-ups. The present model requires the applied load–displacement history and crack extension to generate the crack growth resistance curve ( R -curve). From the generated R -curve, the interface failure load was estimated for the specimens and good agreement with the experimentally recorded value was found.
