Abstract

Uniaxial compression tests were carried out to completely understand the evolution of porosity in porous bulk nanocrystalline materials, and a new evolution law of porosity under uniaxial compression was proposed. Based on the energy principle, we built a mechanical model to calculate the overall mechanical properties of bulk nanocrystalline materials. The comparison between predicted results and the corresponding experimental data indicates that the established model is capable of describing the plastic mechanical behaviors of porous nanocrystalline materials.
