Fracture toughness measurement of dental ceramics using the indentation fracture method with different formulas.
This study examined fracture toughness (KIC) measurements obtained using the indentation fracture (IF) method with a view to improving their reliability. The KIC values of five dental ceramics were measured using the IF method with five different formulas, and the single-edge precracked beam (SEPB) method was used as a control. The elastic moduli of the dental ceramics were evaluated by dynamic...
متن کاملTitanium diboride ceramics for solar thermal absorbers
Titanium diboride (TiB2) is a low-density refractory material belonging to the family of ultra-high temperature ceramics (UHTCs). This paper reports on the production and microstructural and optical characterization of nearly fully dense TiB2, with particular interest to its potential utilization as novel thermal solar absorber. Monolithic bulk samples are produced starting from elemental react...
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 ...
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 کاملconstruction and validation of translation metacognitive strategy questionnaire and its application to translation quality
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
