# Size Effect of Bending Properties of Zirconia Ceramics Based on Cosserat Theory

### Y. Q. Xu, M. M. Li, X. Huo

#### Abstract

In order to study the size effect of zirconia ceramics flexural properties, based on the Cosserat generalized continuum theory, the zirconia ceramic flexural specimens with different heights were numerically simulated, and the intrinsic size parameters of zirconia ceramics were determined by comparing with experimental data. Compared with the classical continuum theory, it is verified that the calculated value of bending strength based on Cosserat theory is closer to the experimental results, which proves that Cosserat theory can explain the size effect of zirconia ceramics flexural strength. The equation of size effect of nominal bending strength and nominal bending stiffness is obtained by numerical regression based on the theoretical values of classical continuum.
