    Abstract

    Two different crush test methods for aluminum honeycombs under compression and shear loads with respect to the out-of-plane direction are presented in this paper. The honeycomb specimen geometry and the test fixtures for the two test methods are first presented. The combined load method used a test frame with two actuators and the inclined load method employed a multiaxial load cell. The experimental results obtained from the two test methods are presented. The experimental results in terms of the normal crush and shear strengths obtained from the combined and inclined load methods are quite consistent. The experimental results also indicate that under inclined loads, neglecting the constraint force can result in significant error, and the error due to the negligence of the constraint force becomes more pronounced as the inclined loading angle and the in-plane orientation angle increase.
