Biaxial flexural modulus of antibiotic‐impregnated orthopedic bone cement

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2007
AbstractPreviously reported antibiotic‐impregnated cement strengths have been based on uniaxial and fatigue testing methodologies. These methods may not provide an accurate characterization of bone cement's true load‐bearing capacity in total joint replacement (TJR).

Hardness, Flexural Strength, and Flexural Modulus Comparisons of Three Differently Cured Denture Base Systems

Journal of Prosthodontics, 2008
Abstract Purpose: This study compared the surface hardness, flexural strength, and flexural modulus of a light‐ and heat‐cured urethane dimethacrylate (UDMA) to two conventional polymethyl methacrylate (PMMA) denture base resins. The effect of less‐than‐optimal processing condition on the hardness of internal and external surfaces of UDMA specimens was

Studies on the flexural modulus of structural foams

Journal of Polymer Research, 1994
An investigation based on I-Beam models was undertaken in this paper for extending knowledge regarding the flexural modulus of structural foam. The applicability of five I-Beams models (I-Beam A, B, C, D and E) including a newly developed one (I-Beam E) were investigated in this work.

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.

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.

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.

Determination of the flexural modulus of elasticity of orthodontic archwires

Dental Materials, 2010
To design a protocol for the determination of the flexural modulus of elasticity of wire with high accuracy and precision.Cantilever bending was used at long span and low loads, using a laser displacement sensor. Various wires were tested for proof-of-concept: stainless steel, Elgiloy, Wiptam and a gold alloy, with primary attention being paid to the ...
