STUDY ON QUASI-STATIC СОMPRESSIVE STRESS OF REINFORCED HONEYCOMBWITH THEORETICS, NUMERICAL SIMULATION AND EXPERIMENT
The quasi-static compressive stress of reinforced honeycomb is studied. Firstly, the structure of the reinforeed honeycomb is analyzed, the Y-shaped cells are extracted, and the plastic hinge is analyzed based on this. Then, referring to the simplified superfolding theory, based on Tresca and Mises yield criterion, the theoretical formula of axial plateau stress is deduced. Thirdly, the aluminum alloy 5052H18 with a wall thickness of 0. 15 mm and a side length of 2. 5 mm is selected, and the honeycomb simulation model is established by Ls-Dyna to obtain the average stress. Comparing the theoretical value with the simulated value, the results show that: under the two yield criteria, the correlation between the theoretical value and the simulation result is 0.96, and the deviation is from -12.16% to 3.60%. Finally, the sample preparation and quasi-static test of ordinary and "4+1"honeycombs shows that the deviation between the theoretical strength and the actual strength of the two specifications is between -2.51% and 1.56%. It shows that the theoretical calculation formula given in this paper is correct, which can provide an effective design basis for the selection of reinforeed honeycombs, and provide a certain guiding value for engineering applications.
