.... To provide insight into selecting appropriate assessment tools for ceramic materials with organized nanoporous architectures, we first compare results from various measurement techniques. Three different techniques were employed; sharp indentation, spherical indentation, and microbending. Hardness values...

... the forming of a complex shaped ceramic powder body with better dimensional control than that achieved by cold isostatic pressing and more uniform density distribution than that by die pressing. The constitutive models proposed by Kim and co-workers were implemented into a finite element program (ABAQUS...

...K. T. Kim, Professor, Assoc. Mem. ASME; S. W. Choi; H. Park Densification behavior of ceramic powder under cold compaction was investigated. Experimental data were obtained for zirconia powder under triaxial compression with various loading conditions. For densification of ceramic powder during...
