Bond strength of metal–ceramic systems in three‐point flexure bond test
Journal of Applied Biomaterials, 1995AbstractThis 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 ...

Adherence evaluation of paint coatings using a three‐point flexure test and acoustic emission
Journal of Applied Polymer Science, 2001AbstractThe 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, 2011The 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.

At the October 1996 meeting of the ISO/TC106/SC 2/WG 1 working group, a special three-point flexure test for the characterization of the metal-ceramic bond was incorporated in the standard (ISO CD 9693). Due to the fabrication process, like real porcelain-fused-to-metal (PFM) restorations, the specimens contain thermal (eigen-) stresses upon which the ...

Influence of bending rotations on three and four-point bend end notched flexure tests
Engineering Fracture Mechanics, 2008Abstract It has been experimentally observed that mode II critical energy release rate (GIIC) values determined by four-point end notched flexure test and three-point end notched flexure test are different for the same material. At the present work correction factors related to bending rotations are introduced to explain the differences between ...

Abstract A three-point flexure test was used to evaluate the effects of chemical surface treatments on the performance of adhesively-bonded structures of Ti6A14V. A single adherend/adhesive structure rather than a double adherend sandwich configuration is shown to be sensitive to pre-bonding adherend surface treatments.

Metal-adhesive bonded systems: Adhesion measurement using a three point flexure test
Journal of Adhesion Science and Technology, 1987Single metallic adherend-adhesive bonded specimens are subjected to a three point flexure test in order to investigate the effects of adherend surface conditioning and adhesive curing conditions on the mechanical properties of the substrate-adhesive interfacial region. The main advantage of this test over more conventional ones (i.e.

Mechanics of Composite Materials, 2003
Effects of different factors on the measured values of flexural modulus and flexural strength of unidirectional carbon/epoxy composites are investigated. This allows a correct interpretation of the results of flexural macromechanical properties obtained in three-point flexure tests.
