WebJan 6, 2024 · Bending elasticities were calculated by measuring the deflections at the middle and quarter-point of the span using center loading. The effects of shear deflection and stress concentration at the loading point on the measured elasticities were compared. WebThe elastic modulus for tensile stress is called Young’s modulus; that for the bulk stress is called the bulk modulus; and that for shear stress is called the shear modulus. Note that the relation between stress and strain is an observed relation, measured in the laboratory.

WebIn mechanics, the flexural modulus or bending modulus is an intensive property that is computed as the ratio of stress to strain in flexural deformation, or the tendency for a material to resist bending.It is determined from the slope of a stress-strain curve produced by a flexural test (such as the ASTM D790), and uses units of force per area. The flexural …
