Hertzian Contact Damage in Porous Alumina Ceramics
A study has been made of Hertzian contact damage in compressive shear stress field beneath the contact area. The observed microcrack density increases with grain size, porous and dense liquid-phase-sintered aluminas. Indentation stress–strain curves show increasing nonlinearity as the implying a threshold microstructural scale for crack initiation. In contrast, the micromechanisms controlling f...
متن کاملFracture Toughness of Ceramics by the Vickers Indentation Crack Length Method: a Critical Review
Fracture toughness is an important property that characterizes a material’s brittleness or resistance to fracture. Although some fracture toughness test methods have been refined and even standardized, many researchers have continued to use the Vickers indentation crack length method as an expedient. In this paper, Vickers indentation fracture resistance data for Standard Reference Material SRM...
متن کاملTheoretical Studies of the Atomic and Electronic Structures of Grain Boundaries in Silicon and Silicon-carbide
The atomic and electronic structures of a facetted twin boundary in Si and a twin boundary in 6-Sic have been studied theoretically for the first time. The atomic structure of the {211}/{111} facets in Si based on the model by Bourret and Bacmann has been optimised by the Keating model, and the electronic structure has been calculated using a supercell technique and a tight-binding model. It ha...
متن کاملStatistical Analysis of Vickers Indentation Fracture Toughness of Y-tzp Ceramics
The purpose of this study was to investigate and analyse the fracture toughness of yttria stabilized tetragonal zirconia polycrystal (Y-TZP) dental ceramics by means of the Vickers indentation technique. Fracture toughness was analysed under the following loads: 29.42 N, 49.03 N, 196.13 N, and 294.20 N. Cracks that had developed from the vertices of a Vickers indentation were measured and used ...
