Effects of aspect ratios of ellipsoidal inclusions on elastic stress transfer of ceramic composites

Journal Article · · J. Am. Ceram. Soc.; (United States)
The elastic stress transfer from a ceramic matrix to aligned ellipsoidal inclusions is analyzed for the case where the axis of the applied load is parallel to the axis of the ellipsoid. Perfect bonding between the matrix and inclusions is assumed. The calculation is based on Eshelby's model for loading of an infinite matrix containing an ellipsoidal inclusion, and the modification to account for the effect of finite volume fractions of inclusions. The results show that the transfer of the axial stress from the matrix to inclusions increases with the increase in the aspect ratio of the ellipsoid, and decreases with the increase in the volume fraction of inclusions when Young's modulus of the inclusion is higher than that of the matrix.
