Title: Fatigue Characterization Of Honeycomb Sandwich Panels With Small Defects
Author: Abbadi, Ahmed; Hadi Meliani, Mohamed; Tixier, Claire; Gilgert, Joseph; Azari, Zitouni
Abstract: The honeycomb sandwich panels are mostly used for their high stiffness, their good fatigue resistance and their low load ratios. In the last several decades, the sandwich structures have increasingly supplanted metals in many structural applications involving aircraft, aerospace, military vehicles, automobiles, civil infrastructure, medical devices, and sporting equipment. In order to characterize 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.
