Residual Strength of Debonded Sandwich Panels Loaded with Lateral Pressure
Experimental Investigation and Fracture Mechanical Modeling
Abstract For the determination of debonded sandwich panel residual strength with lateral loading a parametric finite element model is developed. The parametric model allows an arbitrary positioning of the debond within the panel and consists of both solid and shell elements. A fracture mechanical approach using the crack flank displacements obtained from the FEA solution combined with measured mixed-mode fracture toughness values are used to determine the ultimate failure load. Experiments were conducted to compare against the analysis results. The comparison of numerical and experimentally achieved results showed that the used modeling approach predicts the failure load and failure mode well.
