چکیده

in this paper, collapse behavior of simple and reinforced thin-walled channel- section beams, subjected to three- point bending, is investigated. many simple channel- section beams of different geometry and some reinforced ones were tested, and their strengths after collapse were obtained thoroughly. since the available theories in this area are complicated and little attention has been paid to the case of reinforced thin-walled beams, simple models were used and further developed to give an account of the collapse load and the deformation energy of such beams. the method proposed in this paper is valuable both to the further studies of the symmetric thin-walled beams with arbitrary cross-section and to its practical application of such beams as energy absorbers.

The Effect of Normal Anisotropy on Thin-Walled Tube Bending

Thin-walled tube bending has common applications in the automobile and aerospace industries. The rotary-draw-bending method is a complex physical process with multi-factor interactive effects and is one of the advanced tube forming processes with high efficiency, high forming precision, low consumption and good flexibility for bending angle changes. However, it may cause a wrinkling phenomenon,...

Experimental and Numerical Studies on the Characteristics of Simple and Multi-cell Shapes of Quasi-hemisphere Thin-walled Structures

 Thin-walled energy absorbers are used to reduce accident induced damages. In this study, thin-walled stainless steel structures in quasi-hemisphere geometry were subjected under quasi-static loading with Santam 150KN apparatus. Experimental results were compared with results of numerical simulations by LS-DYNA and it was shown that there is a good agreement between experimental and numerical r...
