  • A fatigue characterization of honeycomb sandwich panels with a defect = Utrujenostna karakterizacija satastih sendvičnih panelov z napako
    Keskes, Boualem ...
    Honeycomb sandwich panels are used because of their high stiffness, good fatigue resistance and low weight. These panels are used in a variety of applications, but particularly in the aerospace ... industry. When this is the case a simple knowledge of the static properties is not sufficient and additional information about the fatigue properties is required. In real situations these panels can be affected by manufacturing defects and impacts, and it is important to know the effects of these defects and the behaviour of the damaged panel; it also important to determine the location of the defect. In our investigation these defects will be simulated by a blind hole in the centre of the lower face sheet. Static and fatigue tests (four-point bending) with acoustic-emission monitoring were carried out on sandwich panels with defects. The load/displacement and the S-N fatigue curves are presented and analyzed.
