Numerical Computation for Effective Mechanical Properties of Honeycomb Core Structure

Abstract:

This paper combined the homogenization method with finite element method. The equivalent mechanical coefficients of the hexagonal aluminum honeycomb core were computed on ABAQUS platform by developing the user subroutine UEXPAN ( ) and Python script file. The results obtained with homogenization method were compared with those obtained with energy method, and it showed the feasibility of homogenization method. Then the effects of thickness-to-length ratio t/l on equivalent mechanical coefficients were taken into account. The results suggested that the equivalent in-plane mechanical parameters vary non-linearly with respect to t/l, while the equivalent out-of-plane mechanical parameters vary linearly with respect to t/l, which will provide reference for optimizing the design of honeycomb core structure.
