Avaliação da tenacidade à fratura de diferentes sistemas cerâmicos
(Journal Of Applied Oral Science : Revista Fob, 2003)
Although ceramics present high compressive strength, they are brittle materials due to their low tensile strength so they have lower capacity to absorb shocks. This study evaluated the fracture toughness of different ceramic ...
Design Equations for Mixed-Mode Fracture of Dental Ceramic–Cement Interfaces Using the Brazil-Nut-Sandwich Test
(2021-10-01)
Dental interfaces are subject to mixed-mode loading. This study provides practical guidance for determining interfacial fracture toughness of dental ceramic systems. We address interfacial fracture of a composite resin ...
Effect of processing induced particle alignment on the fracture toughness and fracture behavior of multiphase dental ceramics
(ELSEVIER SCI LTD, 2009)
Objective. To investigate the processing induced particle alignment on fracture behavior of four multiphase dental ceramics (one porcelain, two glass-ceramics and a glass-infiltrated-alumina composite). Methods. Disks ...
