Abstract

Glass fiber face sheet/balsa wood core sandwich beams with out-of-plane fiber misalignments/wrinkle defects were subjected to in-plane fully reversed fatigue loading and the failure modes were documented. A fatigue life design limit was estimated using finite element analyses and the Northwestern University failure theory. The presence of the wrinkle defect significantly lowered the fatigue strength, but it was found that the test specimens could reach a pre-defined fatigue life with no signs of damage, by applying a fatigue load below 80% of the estimated design limit.
