The present study has been aimed to combine the advantages of the two single-phase materials, Al2O3 and ZrO2 while avoiding their disadvantages, by producing a mixed ceramic.
Introduction Alumina and zirconia ceramics have been successfully used as materials for joint endoprostheses.
The coupling of ZrO2 with Al2O3 components, used with varied results, is under debate, too. [3] Material and Methods The present study has been aimed at combining the advantages of the two single-phase materials, Al2O3 and ZrO2 while avoiding their disadvantages, by producing a mixed ceramic.
This high-strength, thermodynamically stable material is necessary for the manufacture of products that have so far been the domain of metallic materials alone.

The finite deformation about the radial direction is examined for a solid cylinder composed of a class of compressible hyper-elastic materials.
Theoretically, a comprehensive review of results up to 1995 for hyperelastic materials was presented by Horgan and Polignone [3] and up to 2005 by Yuan et al[4].
The purpose of this paper is to study the cylindrical cavitation at the axial line of the solid cylinder composed of a class of compressible hyper-elastic materials.
