“…The identification of the stress-strain law in direct tension is of primary importance to generalize the results coming from experimental testing, and several approaches can be found in the literature [13][14][15][16][17][18]. In this regards, direct tensile test is generally considered the most reliable test, but it is rather complex to be implemented and very sensitive to possible defects and eccentricity in loading [16].…”

“…On the other hand, flexural test is much easier to be implemented, proving also a much higher repeatability. This latter test, however, is characterized by sizable structural effects caused by stress redistribution in the section, thus making rather difficult the backward identification of the material mechanical properties [16,18].…”

“…The first method is called simplified inverse analysis which assumes a bi-linear stress-strain constitutive relationship and consists in an iterative process by varying the constitutive parameters until the analytical curve fits the experimental one. Many researchers focus to develop new simplified methods to improve the AFGC's simplified method by using analytical models based on tri-linear stress-strain constitutive law, quadrilinear, and multi-linear assumptions of the tensile behavior [5,32,35,36,37]. The second and the third methods proposed by AFGC use different experimental measurements (strain measurement at the bottom fiber or deflection measurement) as data input in their proposed analytical model.…”
