Abstract
A calculation method is firstly proposed to describe the mechanical behavior of an individual phase of multi-phase nanocrystalline ceramics, and then Budiansky's self-consistent method is applied to calculate the elastic modulus of porous, multi-phase nanocrystalline ceramics. Further, the established method is extended to describe the stress-strain relations with small plastic deformation, and then the yield strength (σ0.2) of porous, multi-phase nanocrystalline ceramics can be determined. In a word, the predictions are in good agreement with the results in the literature.
