Finite Element Calculation for the Tensile Elastic Modulus of Honeycomb Materials with Different Pore Shape

Abstract:

The square and hexagonal honeycomb materials were studied by finite element simulation of tensile test in order to calculate the elastic modulus in tension under different porosity and to analyze tensile properties affected by the pore shape of honeycomb materials. Research results show that the tensile elastic modulus of the square honeycomb is larger than the hexagonal honeycomb. The reason is that the square structure has a larger stiffness than hexagonal structure. Also, the equivalent elastic moduli of calculated values are higher than the theoretical values, because the finite element model is based on solid elements while the theoretical model is based on the Euler beam.
