J. Cent. South Univ. (2016) 23: 2110-2117 DOI: 10.1007/s11771-016-3267-x Bending behaviour of lightweight aggregate concrete-filled steel tube spatial truss beam FU Zhong-qiu(傅中秋)1, JI Bo-hai(吉伯海)1..., Japan Central South University Press and Springer-Verlag Berlin Heidelberg 2016 Abstract: A lightweight aggregate concrete-filled steel tube (LACFST) spatial truss beam was tested under bending load......
Elasto-plastic finite element analysis of squaring circular tube HUANG Yuung-ming(黄永明) Department of Mechanical and Computer-Aided Engineering, St. John’s University, Taipei 25135, China... deformation theory was established, and Lagrangian formulation for simulating the squaring process of circular tube was updated. Incremental Coulomb’s friction law was used in the global stiffness matrix......
Undercooling and rapid solidification of Nb-Si eutectic alloys studied by long drop tube WANG Yu-ren(王育人), DONG Shu-yong(董树勇), WEI Bing-chen(魏炳忱), LI Wei-huo(李维火) National Microgravity Laboratory... turbine applications. The two-phase Nb/Nb5Si3 in situ composites exhibit a good balance in mechanical properties. Using the 52 m drop tube, the effect of undercooling and rapid solidification......
