The indicator was defined as the second moment of the normalised curvature function about the mid-span, where the curvature was computed from the normalised deflection function. Elastic reference values of the indicator were computed for simply supported beams under uniformly distributed load, three-point, and four-point bending. Development of the indicator under progressive loading was examined with the help of finite element analyses. The indicator value monotonically decreased with increasing deformation provided that maximum bending moment was located between 0.41L and 0.59L, where L is the span of the beam. In this interval, the value of the indicator was unique and enabled the direct monitoring of the post-elastic stress level in the cross-section. 2023-04-17T04:42:19Z 2023-04-17T04:42:19Z 2023 Book https://link.springer.com/article/10.1007/s40999-022-00800-6 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7992 en application/pdf Springer
