Improvement Design for A Double-Layer Honeycomb Structure using Uniform Design for Static and Dynamic Stress Analysis

The objective of this article is to enhance the intensity of a double-layer honeycomb structure (HCS) under static forces and dynamic impact loads using the design of experiment method. A collection of simulation experiments is conducted using the uniform design (UD) method. The maximum von Mises stresses (VMS) in the honeycomb core (HCC) are calculated under ASTM tension and compression testing rules using static finite element analysis (FEA) through ANSYS/Workbench software. Dynamic FEA is employed to evaluate the maximum deformation of the HCS under the ASTM impact load testing simulation using ANSYS/LS-DYNA. In order to upgrade the energy absorption performance of the HCS, the maximum deformation of the HCC needs to be reduced under impact loads. Therefore, four objectives are considered simultaneously. The improved design of the double-layer HCS is obtained after executing the uniform design (UD). For the ASTM C297, C364, C365, and D7766 simulations, the improved design results in 15.4%, 29.78%, 3.29%, and 23.98% improvements over the original design, respectively. Subsequently, the UD technique creates a stronger double-layer HCC in the HCS.
