The relation between impact strength and flexural strength of dental materials

open access: yesJournal of the Mechanical Behavior of Biomedical Materials, 2021
The aim of this study was to investigate whether there is a relation between impact strength and flexural strength of different composite and ceramic materials used in dental restorations.The three-point-bending test was used to determine the flexural strength and flexural modulus, and the Dynstat impact test was used to determine the impact strength ...

Mechanical performance of glass-based geopolymer matrix composites reinforced with cellulose fibers [PDF]

open access: yes, 2018
Glass-based geopolymers, incorporating fly ash and borosilicate glass, were processed in conditions of high alkalinity (NaOH 10-13 M). Different formulations (fly ash and borosilicate in mixtures of 70-30 wt% and 30-70 wt%, respectively) and physical ...

Flexural strength and hardness of direct and indirect composites [PDF]

open access: yesBrazilian Oral Research, 2009
The objective of this study was to evaluate the flexural strength (sigma f) and hardness (H) of direct and indirect composites, testing the hypotheses that direct resin composites produce higher sigma f and H values than indirect composites and that these properties are positively related.
