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, 2005The 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 fatigue testing of polyesters
Journal of Applied Polymer Science, 1963AbstractA 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, 1997The 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, 1991Four-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 ...

Analysis of the Time Dependent Flexural Test
1975The flexural test was analyzed for the general case of a time dependent arbitrary law of deformation. This analysis relates the outer fiber stresses to measured values of moment and time. In lieu of knowledge of the exact relationship between the tensile and compressive stresses, two boundaries were established within which the analyses for most ...

Analysis of The Flexure Test of Bidirectional Composites
Journal of Composite Materials, 1967Equations are presented which permit a more realistic evalua tion of flexure experiments on bidirectional composite beams. The influence of shear deflection is discussed, and predicted results are compared to experimental data.
