Residual Strength of In-Plane Loaded Debonded Sandwich Panels: Fracture Mechanical Modelling

Berggreen, Christian / Simonsen, Bo Cerup

Abstract This paper presents a FEM based numerical model for prediction of residual strength of damaged sandwich panels. As demonstrated, the model can predict the maximum load carrying capacity of real-life panels with debond damages, where the failure is governed by face-sheet buckling followed by debond growth. Comparison of the theoretical predictions is carried out against a series of large-scale experiments described in Lundsgaard-Larsen et al. [1].
