Abstract

Graphical abstract: Abstract: In order to characterise efficiently the honeycomb sandwich panels, the static behaviour does not seem to be sufficient and additional information about fatigue data properties is needed. This study presents an important experimental fatigue data for honeycomb sandwich panels with artificial defects and without defects. The results from the fatigue tests on honeycomb sandwich panels are compared to those of the aluminium alloy skin (the reference case). Experimental results showed that: - The presence of defect has no influence on the static behaviour of the material. - The lifetime of the L configuration is larger than in the W-direction. - The lifetime of sandwich panels is very sensitive to drilling hole type defect than Brinell one.
