Analysis for Enhancing the Performance Characteristics of Honeycomb-Filled Tubes at Constant Mass

Abstract

In this paper, assuming the lightweight design is the main requirement, an efficient design of honeycomb sandwich tubes and its quasi-static compressive properties improvement were presented. The structures are designed in SolidWorks software, consisting of two face sheets and a honeycomb core implemented in its in-plane position. The axial compression tests are performed using Abaqus software. Detailed deformation features and energy absorption characteristics during the crushing process were presented. The compressive properties of the improved structures were determined from the energy absorption efficiency curves. Additionally, mathematical formulas for predicting the quasi-static compressive properties are presented. Theoretical predictions and FEA findings were in good agreement. In comparison to the standard structure, the suggested method greatly increased the structure's strength without adding mass to the design.
