J. Cent. South Univ. (2018) 25: 1774-1785 DOI: https://doi.org/10.1007/s11771-018-3868-7 Numerical and experimental study on seismic behavior of concrete-filled T-section steel tubular columns... properties of the planar frames. Two 1:2.5 reduced-scale specimens of T-section concrete-filled steel tubular column and steel beam of single-story and single-bay plane frames were designed......
into functional tubular micro- components, a more efficient shaping process is required to convert a basic extruded polymeric tube into a more complex component-form. This effect would add values and increase functionality of micro-tubes, which is being addressed in the EU FP7 POLYTUBES project [9]. A typical example is the use of polymeric tubular component as a filter in a medical instrument......
Trans. Nonferrous Met. Soc. China 22(2012) s280-s286 Mechanics condition of thin-walled tubular component with rib hydroforming CHU Guan-nan1,2, YANG Shuai3, WANG Jian-xun2 1. State Key Laboratory... was derived for rib which is restrained at one end and free at the other. The results indicate that it is possible to achieve a sound thin-walled tubular with rib component through hydroforming process and its......
