Effect of thermal treatments on tensile strength of commercially cast pure titanium and Ti-6Al-4V alloys
Heating titanium structures is assumed to relieve tensions induced by the casting process as well as possibly optimizing some mechanical properties. The aim of this investigation was to evaluate the effect of thermal ...
Tensile bond strengths of hard chairside reline resins as influenced by water storage
Due to gradual resorption of the edentulous ridge bone, removable prostheses often require denture base relines to improve fit and stability. This research evaluated the bond strength between one heat-cured acrylic resin ...
Influence of ultrasonic setting on compressive and diametral tensile strengths of glass ionomer cements
(ABM, ABC, ABPol, 2008)
The aim of this study was to assess the influence of ultrasonic wave propagation on the compressive (CS) and diametral tensile (DTS) strengths of glass ionomer cements (GICs). Three variables were evaluated: conventional ...
Shear modulus G(0) and its correlations with matric suction, unconfined compression strength and tensile strength of an unsaturated residual soil
(Ios Press, 2015-01-01)
Several studies have been developed aiming to understand the behavior of saturated natural soils under small strains. A few studies have considered unsaturated soils, in most cases compacted soils and, eventually, disregarding ...
Orthodontic brackets removal under shear and tensile bond strength resistance tests - a comparative test between light sources
(Wiley-v C H Verlag Gmbh, 2008-01-01)
We have investigated if a new LEDs system has enough efficient energy to promote efficient shear and tensile bonding strength resistance under standardized tests. LEDs 470 +/- 10 nm can be used to photocure composite during ...
Diametral tensile strength of dual-curing resin cements submitted exclusively to autopolymerization.
OBJECTIVES: To evaluate, at different times, the diametral tensile strength (DTS) of dual-curing resin cements that were not photopolymerized. METHOD AND MATERIALS: Equal amounts of base and catalyst pastes of Panavia F ...
Effects of Chlorhexidine and Fluoride on Irradiated Enamel and Dentin
(Sage Publications IncThousand OaksEUA, 2011)
Optimization of Pultrusion Process Parameters via Design of Experiments and Response Surface
Experimental designs were implemented to investigate the effects of mold temperature and pulling speed on the tensile strength of cylindrical cables produced by pultrusion. A two-level factorial design with a central point ...
