Evaluating the Applicability of GTN Damage Model in Forward Tube Spinning of Aluminum Alloy
Tube spinning is an effective plastic-forming technology for forming light-weight, high-precision and high-reliability components in high-tech fields, such as aviation and aerospace. However, cracks commonly occur in tube spinning due to the complexity of stress state, which severely restricts the improvement of the forming quality and forming limit of components. In this study, a finite elemen...
متن کاملFlexible Forming of Thin Aluminum Alloy Sheets
Flexible forming is a sheet metal forming process with the application of soft material tooling. In this study, flexible (silicone rubber, SR, and styrene butadiene rubber, SBR) and semi-rigid (polyamide 66, PA) polymeric materials were adopted to make several upper dies which were used in combination with aluminium lower dies. Stamping operations were performed on a thin aluminium alloy sheet ...
متن کاملElectronic Properties of Ultra-Thin Aluminum Nanowires
We have carried out first principles electronic structure and total energy calculations for a series of ultrathin aluminum nanowires, based on structures obtained by relaxing the model wires of Gulseren et al [1]. The number of conducting channels is followed as the wires radius is increased. The results suggest that pentagonal wires should be detectable, as the only ones who can yield a channe...
متن کاملFabrication of Aluminum Foam-Filled Thin-Wall Steel Tube by Friction Welding and Its Compression Properties
Aluminum foam has received considerable attention in various fields and is expected to be used as an engineering material owing to its high energy absorption properties and light weight. To improve the mechanical properties of aluminum foam, combining it with dense tubes, such as aluminum foam-filled tubes, was considered necessary. In this study, an aluminum foam-filled steel tube, which consi...
متن کاملMorphology-induced plasmonic resonances in silver-aluminum alloy thin films
We have investigated the optical properties of sputter-deposited silver-aluminum alloy thin films on silicon substrates at room temperature. In addition to the primary feature that corresponds to the bulk plasma resonance, a secondary dip appears in the optical reflectance spectra, which shifts and diminishes with thermal annealing. Careful structural characterization of both the as-deposited a...
