This paper is concerned with investigating of the plastic behaviour on gap K-joints truss girders, made from thin-walled rectangular hollow section members. An experimental study was carried out a full-scale girder under concentrated load two central nodes. A numerical analysis using ABAQUS in order to clearly see this type joint and make comparison experimentation. will it possible examine att...

A cylindrical transmembrane molecule is constructed by linking hydrophobic sites selected from a coarse grain model. The resulting hollow tube assembly serves as a representation of a transmembrane channel, pore, or a carbon nanotube. The interactions of a coarse grain di-myristoyl-phosphatidyl-choline hydrated bilayer with both a purely hydrophobic tube and a tube with hydrophilic caps are stu...

Abstract In this study, a kind of structural gradient metal hollow spheres composites (SG-MHSCs) were fabricated using two kinds 316L stainless steel with different diameters and A356 aluminum through the casting method. Then density SG-MHSCs was measured by direct measurement; microstructure characterized Scanning Electron Microscope. Meanwhile, acoustic performance MHSCs tested impedance tube...
