Abstract
Static and fatigue behaviors of Nomex honeycomb sandwich structures were characterized by compression and bending experiments. And the finite elemental numerical simulation research was carried out based on the test data. The load level for fatigue test was determined and the necessary stiffness information for the construction of finite element model was provided by the study of static load performance. The fatigue failure mode and damage mechanism of Nomex honeycomb sandwich structures were analyzed by comparing the fatigue life curves and experimental phenomena of bending fatigue and compression tests. This study presented a method to predict the fatigue life of honeycomb sandwich structures and its feasibility was verified by experiments.
