Therefore, the mechanical work done by the external force can be equated to the bending energy along the crease lines, with some energy dissipation. Although a number of researchers have investigated the use of origami tubes for energy absorption, most of the studies relied on a quasi-static ...

wrapped object and steel tube of tower column are all made of Q235 steel; The two pieces of wrapped objects are processed and shaped by the steel plate bending technology at one time, the bolts of two wrapped objects, and between the plate of ball table and pressure plate are made of M20...
An arrangement of apparatus for producing a straight bore cold drawn tube, where the internal surface of the finished tube has a minimum of surface wave. This is accomplished by extending the mandrel
A solution for the pure plane strain bending of a sheet has been derived in [6]. This solution has been extended to plane strain bending under tension in [7]. No restriction on the strain hardening law has been imposed in [6,7]. Paper [8] has further extended the solution to include...
In ASME, the structural stress is expressed as the function of the membrane stress and the bending stress perpendicular to the hypothetical potential crack, while in EN, it is defined as the sum of the primary stress and the secondary stress. For Method 4, the notch stress is applied to ...
The object of this note is to complete the analysis by developing corresponding formulas for the horizontal and vertical deflections, and the rotations, of a framed-tube structure subjected to standard bending and torsion load cases. 展开 关键词:...
Performance indices are proposed to quantify the section, axial ductility and curvature ductility performance of thin-walled CFST beam–columns under axial load and biaxial bending. Efficient secant algorithms are developed to iterate the depth and orientation of the neutral axis in a thin-walled CF...
Based on the form of the calculation formula recommended by CISC, the calculation formula for the bending capacity of the K joints was fitted. The calculation results obtained from the fitted formulas in this paper show agreement with the numerical simulation results. 2. Experimental program 2.1. ...
2.4. Bending Test of Bionic Tubes The bending tests were conducted by using an electronic universal testing machine (Instron, Canton, MA, USA). To reproduce the operating conditions of the finite-element simulations and facilitate the fixed test on the test machine, the telescopic fixture made of...
