“…The predictions obtained from this gave excellent results in terms of failure loads and reasonable accuracy in the kink band lengths. In a sub-sequent paper, Edgren et at [38] performed a similar but more refined analysis of the same experiments.…”

This paper is a review of activities concerning various damage tolerance modelling and testing aspects of sandwich panels for typical Naval applications. It starts with a review of testing methods for primarily core materials and how to extract properties and data required for damage tolerance assessment. Next some typical damage types are defined and how they are modelled with the aim of predicting their effect on load bearing capacity. The paper then describes in brief how such models can used in the context of providing a systematic damage assessment scheme for composite sandwich ship structures.

“…Failure was fibre dominated and occurred suddenly at two locations where the radii of the dog bone meets the gauge section, triggered by the stress raiser and the notch sensitive nature of the material [39]. The standard deviation between strain profiles from the two corresponding surfaces, for each specimen, was less than 20% in each case.…”

“…The section relies on previous investigations on impact-damaged sandwich panels for naval ships and monolithic aircraft-type laminates at Swerea SICOMP (Edgren et al , 2004b;Edgren et al , 2008;Edgren, 2005). In the second part, damage propagation to failure for these materials in subsequent in-plane compression-loaded residual strength tests is discussed.…”
