Flexural Behavior and Fracture Characteristics of Polymeric Pipes Under Curved Three-Point Bending (CTPB) Tests

, 2021
This study describes an investigation of the load-deflection response of polymeric pipe material. Three point bending tests were performed on curved samples extracted directly from the studied pipes to evaluate their flexural properties, namely the flexural strength, the modulus, the strain to failure, the stress intensity factor, the fracture energy ...

The Flexural Behavior Study of Composites Material in Static Three-Point Bending Test

Advanced Materials Research, 2012
The effect of the plies number and the thickness on flexural properties of glass fiber reinforced polyester or epoxy composites has been investigated experimentally. Laminates were fabricated by hand layup technique in a mould under light pressure and followed by curing at room temperature for 8 hours.

Flexural strength and modulus of a novel ceramic restorative cement intended for posterior restorations as determined by a three-point bending test

Acta Odontologica Scandinavica, 2003
The aim of this study was to compare a new restorative cement intended for posterior restorations, Doxadent, with other types of tooth-colored materials as regards flexural strength and flexural modulus. The new restorative material consists mainly of calcium aluminate.

Model for estimating the flexural performance of concrete reinforced with hooked end steel fibers using three‐point bending tests

Structural Concrete, 2021
AbstractThe behavior of fiber reinforced concrete (FRC) depends on the characteristics of both the concrete matrix and fibers. Previous studies have concluded that the number of hooked ends increases the contribution of steel fibers to the tensile performance of concrete. ACI 318 code, MC10 fib code and RILEM TC 162‐TDF standard permit the use of steel

On the three-point flexural tests of dental polymeric resins

Bio-Medical Materials and Engineering, 1997
Currently acrylic resins are commonly employed in many medical applications, especially for the fabrication of long span provisional restorations in dentistry and bone cement in orthopedics. On of the major problems associated with the conventional type of acrylic resins is their unsatisfactory mechanical properties.

Three-Point Bending Device for flexure testing of soft tissues

2009 IEEE 35th Annual Northeast Bioengineering Conference, 2009
This 3-Point Bending Device is intended to provide the user with a novel tool used to obtain material property information for biological tissues. Specifically, the device is intended to provide the user with the stress-strain relationship of the tested tissue in the low-strain region (≪5% strain) and provide the location of the neutral axis.

Bond strength of metal–ceramic systems in three‐point flexure bond test

Journal of Applied Biomaterials, 1995
AbstractThis study deals with a three‐point flexure test for the metal‐ceramic bond involving geometrically simple specimens (alloy strips partly coated with ceramic) that can be fabricated with reasonable expenditure and sufficient reproducibility. The calculation of the stress distribution in such specimens with the aid of the finite‐element method ...

Flexural strengths of conventional and nanofilled fiber‐reinforced composites: a three‐point bending test

Dental Traumatology, 2013
AbstractObjectivesThe purpose of this study was to evaluate the effect of the introduction of nanofillers on the mechanical properties of fiber‐reinforced composites (FRCs) for stabilization and conservative treatment of multiple traumatized anterior teeth. In particular, the aim of the research was to point out the force levels of two sizes (diameters

Adherence evaluation of paint coatings using a three‐point flexure test and acoustic emission

Journal of Applied Polymer Science, 2001
AbstractThe adherence of paint coatings on aluminum substrates was tested using a three‐point flexure test (TPFT) combined with acoustic emission (AE) evaluation. The mechanical test was defined according to the French Standard. During bending of the paint‐coated specimen, acoustic emission signals were recorded and analyzed.

A novel approach for the three-point flexure test of multidirectional laminates

Journal of Composite Materials, 2011
The complementary energy of a multidirectional laminate is obtained as a function of mechanical and hygrothermal force and moment resultants. Three-point flexure is then analysed assuming that the specimen is in contact with the support rollers at four points.
