View PDF View article View in Scopus. 6. S . Flexural Strength. The flexural strength of a material is obtained when one loads a simple single beam, simply supported (not fixed) at each end, with a load applied in the middle (Figures 5-3 and 5-4).Such a test is called a three-point bending (3PB) or flexure test and the maximum stress measured in the test is called flexural strength. The flexural strengths for .Torsion Testing Equipment. Torsion testing can be performed on any one of several different testing systems depending on the specific application.
