摘要：
In order to overcome the low precision of analytic formulas for equivalent elastic modulus of honeycomb, the in-plane deformations of honeycomb are simulated numerically through finite element analysis (FEA) software Ansys. The representative volume element (RYE) is firstly selected and modeled in 3D, according to the repetition of honeycomb cell. Then the deformations of RYE under three different boundary conditions are discussed on several premises. And the equivalent elastic modulus of two specifications of honeycomb from experiments, analytic formulas of Gibson and FEA's simulation results are presented and compared, adequately proving the effectiveness of the above method. Finally, the fitting formulas of equivalent elastic modulus that are convenient for engineering application are proposed by analyzing series of different sizes honeycomb.
