This paper uses the Split Hopkinson Pressure Bar (SHPB) test to analyze the aluminum honeycomb's dynamic and failure behavior under different strain rates. At the same time, we propose a modeling method. The representative volume element (RVE) models the complex materials. On this basis, the equivalent material parameters of complex materials are calculated. Taking the aluminum honeycomb material as an example, we use the equivalent material parameters calculated by the representative volume element of aluminum honeycomb to construct the macro-model of the aluminum honeycomb and compare it with the refined model of aluminum honeycomb. According to the SHPB test of aluminum honeycomb, the finite element models are compared and calibrated, and the accuracy of the finite element model is verified. It is expected to provide a reference for applying aluminum honeycomb materials in various fields, the dynamic behavior of aluminum honeycomb, and the combined use of multi-scale finite element modeling. |
