Efeito da concentração de ácido fluorídrico na carga para falha em fadiga de uma cerâmica feldspática cimentada
(Universidade Federal de Santa Maria, 2018-03-16)
The present thesis is composed by two scientific articles that evaluated the influence of
different hydrofluoric acid concentrations on the fatigue failure loads of feldspathic ceramic
crowns and discs adhesively cemented ...
Comportamento à fadiga de materiais cerâmicos
(Universidade Federal de Santa Maria, 2016-12-09)
Two manuscripts about the fatigue behavior of ceramic materials are reported in this thesis. Manuscript 1: Impact of the CAD/CAM machining on the fatigue behavior of glass and polycrystalline ceramics. This study assessed ...
Comportamento mecânico em fadiga de YSZ: efeitos de diferentes tratamentos de superfície e materiais a base de zircônia
(Universidade Federal de Santa Maria, 2019-11-29)
This thesis are composed of four studies: study 1 – evaluation of fatigue failure load, number of
