Abstract

The micromechanical model for predicting the equivalent macroscopic characteristic parameters of aluminum honeycomb core is established based on homogenization theory combined with finite element method.The effects of the aluminum honeycomb cell structural parameters on its macroscopic equivalent characteristic properties are investigated.And by using MATLAB software,the equivalent elastic parameters of irregular orthotropic hexagonal aluminum honeycomb cores with various high-to-length ratio,thickness-to-length ratio and cell wall angle are calculated.The effects of cell structural parameters on its macroscopic equivalent mechanical properties are obtained.The results have guiding signification for the structure design of aluminum honeycomb core and its engineering application in wind turbine blades.
