| Summary: | The spherical nanoindentation macroscopic stress–macroscopic strain relationship of hierarchical honeycomb nanoporous material is defined by combining the spherical nanoindentation simulation and the uniaxial compression simulation. At the same time, the macroscopic elastic modulus and the macroscopic yielding stress of the hierarchical material are obtained from the curves through different methods. The results show that the macroscopic stress–macroscopic strain curve of the hierarchical nanoporous materials nanoindented to a depth of 30 nm is basically consistent with the curve of the hierarchical nanoporous materials when uniaxially compressed down to 25 nm. Through the nanoindentation and uniaxial compression, the macroscopic elastic moduli and the macroscopic yielding stresses are also close to the scale formula. |
