Comparison of flexural properties of composite restoratives using the ISO and mini-flexural tests

Journal of Oral Rehabilitation, 2003
summary  The purpose of this study was to investigate the flexural properties (flexural strength and flexural modulus) of four commercial composite restoratives (Silux Plus, Z100, Ariston and Surefil) using the ISO 4049 flexural test (IFT) and a mini‐flexural test (MFT). Both tests involved the use of three‐point loading and the same fixture.

Flexure Test for Determination of Tablet Tensile Strength

Journal of Pharmaceutical Sciences, 1974
A new method for determining the tensile strength of tablets is proposed utilizing two fulcrums and a knife edge. The fulcrum and knife edge pieces were affixed to the platens of a motorized tablet hardness tester. The new method was found to give rapid, reproducible results which agreed well with tensile strength values obtained from diametral ...

Protocol for Testing Flexural Strength, Flexural Modulus, and Fatigue Failure of Cementitiously Stabilized Materials Using Third-Point Flexural Beam Tests

Geotechnical Testing Journal, 2016
Abstract In this study, a testing protocol was developed to measure the flexural strength, flexural modulus, and fatigue failure of cementitiously stabilized materials (CSMs) for both lightly and heavily stabilized soils. Four soils (sand, gravel, silt, and clay) and four binders (cement, lime, class C fly ash, and class F fly ash) were ...

Flexure-based Micromechanical Testing Machines

Experimental Mechanics, 2005
The successful design and fabrication of structures and systems at the small scale require robust methods for characterizing the mechanical behavior of materials at the same scale. In this paper we describe the design of two flexure-based micromechanical testers capable of measuring forces with an accuracy of 25 μN over a range of 1–30 N, and specimen ...

Flexural tests of Mi Panels

2014
Two series of flexural tests on 2700x600x75 mm Mi Panels are presented. The inner core of these lightweight panels is made from mixing polystyrene beads called Neopor, high strength cement, and water. A chemical is used as binding agent to bond the inner core to the external fibre cement sheets of 4.5 mm thickness.

Flexural fatigue testing of polyesters

Journal of Applied Polymer Science, 1963
AbstractA method is described for evaluating flexural fatigue properties of unsaturated polyesters. With the use of the Sonntag fatigue machine and a modified version of the Prot principle, dynamic parameters and fatigue properties can be readily determined.

Flexure tests on dental ceramics.

The International journal of prosthodontics, 1997
The failure stresses in flexural tests of a densely sintered high-purity alumina (Procera AllCeram) were evaluated using three-point bend, ring-on-ring, and piston-on-three-ball tests. Glass-infiltrated presintered alumina (In-Ceram) and leucite-reinforced porcelain (IPS Empress) disks with the same dimensions were also tested using ring-on-ring and ...

Biaxial flexure testing of brittle materials

Scripta Metallurgica et Materialia, 1991
Four-point bending tests are one of the primary methods of strength testing glass and ceramic materials. However, four-point bend test bars are susceptible to failure from edge cracks unless extreme care is taken in sample preparation. For that reason, biaxial flexure tests have gained increasing popularity for strength measurements in brittle ...
