Flexural strength and modulus of a step‐cured resin composite

Acta Odontologica Scandinavica, 2004
In an attempt to reduce marginal contraction gaps, a step-curing mode of light polymerization of resin composite has been proposed. It was hypothesized that such an exposure mode, having an initial reduced curing rate, would result in composite having a lower modulus of elasticity than composite exposed in one step.

Study on Flexural Strength and Flexural Modulus of Elasticity of Cement Stabilized Aggregate

Advanced Materials Research, 2011
The aim of this study was to study the effect of curing period and cement content of the specimen on flexural strength and flexural modulus of elasticity of cement stabilized aggregate. Four specimen curing periods (7 d, 14 d, 28 d and 60 d) and four different cement contents (4%, 5%, 6% and 7%) were used.

Potential model of the modulus of elasticity in flexure for plywood

Wood Science and Technology, 1995
Once the modulus of elasticity (MOE) when calculating the bending properties of plywood is obtained, the result is one of the requirements necessary in order to characterize these panels. For this purpose the A.S.T.M. D-3043 Standard establishes the span between the supports and the geometric characteristics of the samples.

Flexural Modulus of Symmetric and Asymmetric Structural Foams

Journal of Cellular Plastics, 2009
In this work, the preparation and characterization of symmetric and asymmetric structural foams is presented. Using low-density polyethylene and modified azodicarbonamide, a compression molding technique is presented to produce structural foams while controlling the skin thickness on both sides.

The influence of resin flexural modulus on the magnitude of ceramic strengthening

Dental Materials, 2012
The aim was to determine the magnitude of ceramic resin-strengthening with resin-based materials with varying flexural moduli using a regression technique to assess the theoretical strengthening at a 'zero' resin-coating thickness. The hypothesis tested was that experimentally, increasing resin flexural modulus results in increased resin-strengthening ...

Effect of MTAD on Flexural Strength and Modulus of Elasticity of Dentin

Journal of Endodontics, 2003
The purpose of this study was to evaluate the effect of MTAD on the flexural strength and modulus of elasticity of dentin. Dentin bars were randomly assigned to eight groups treated with various concentrations of NaOCl (5.25%, 2.65%, 1.31%, 0.66%), 17% EDTA, MTAD, saline, or according to a clinical protocol with 1.3% NaOCl and then 5 min of MTAD ...

Young's Modulus of Elasticity of Ceramic Materials by Flexure

Transactions of the Indian Ceramic Society, 1952
AbstractThe study of the effect of several variables affecting the determination of E-modulus by flexure was undertaken in order to remove the inadequacy of the testing procedure, and to gain a more intimate knowledge of their significance. The diameter, span-depth ratio, heat treatment, porosity, bulk density etc.

Comparison between flexural and tensile modulus of fibre composites

Fibre Science and Technology, 1984
Abstract The difference between flexural and tensile Young's modulus, as experienced experimentally, is analysed theoretically. It can be explained by large shear deformation and a heterogeneous section, making the formulae from elementary bending of beams incorrect.
