According to the measured bending moment capacity (Mue) and the calculation of curvature (φ) by formula (3), the M-φ curves can be plotted in Fig. 6. The initial stiffness Kie is taken as the corresponding secant bending stiffness when M = 0.2Mue28. The bending stiffness (Kse) ...
The paper introduces a bend test model and its execution method and calculation formula derivation, and explains the test method precision and feasibility ... LM Zhang - 《Tianjin Metallurgy》 被引量: 0发表: 2013年 Bending method for thin-walled steel pipe with rectangular section The invention ...
In the following, formulae about the design resistance and stability of equal-leg angle members as derived during the ANGELHY project, are presented, discussed and compared with the Eurocode 3 provisions. In absence of the availability of analytical solutions for general application, they constitute...
The correctness of the theoretical prediction formula was verified by experiments. Although researchers have been devoting themselves to the study of the axial impact performance of thin-walled structures and designed effective energy absorption devices, the progressive buckling failure of the axial impact...

(POFs) have so far only been documented by experimental work, investigating bending parameters such as bending radius, length, and distance of the bends. Even though damping mechanisms and causes are well-known, no simple, generally valid formula exists. Here, a simulation technique is shown ...
The calculation of the ultimate bending moment in the plastic state of both materials (steel, concrete) was estimated with a formula derived from torques, Eq. (11), where, as in the former section, d is 260 mm and d’ equals 26 mm, and the factor, 0.4, is derived from the position...
, or the valley to the peak, meaning a half-period. Therefore, the overall displacement can be figured out by counting the number of half a periodN, andL1 + L2stands for the minimum resolution. In addition, the voltage signal’s frequency can be expressed as the following formula:...
