Interface fracture assessment on honeycomb sandwich composite DCB specimens

► Modified elastic foundation model to analyse sandwich DCB specimens. ► Validation of the model by performing the complex 3D finite element analysis. ► Improved procedure is proposed for evaluating the interface fracture toughness. ► Failure load estimates of sandwich DCB specimens match well with...
