The idea is to combine the intrinsic and novel properties of nickel–titanium shape memory alloys with purposely engineered topologies. By joining thin-wall superelastic tubes via electrical resistance welding, we create regular cellular material demonstrators. The superelastic behavior of two simple architectured materials based on identical tubes, but with two topologies, are experimentally characterized and modeled using finite element approaches. The predicted behaviors are compared by simulating complex loading, exploring the influence of the constitutive material behavior on the effective mechanical properties of cellular materials. The parameters of the constitutive equations are identified on tensile tests performed on small dog-bone shaped specimens, machined from the tubes by spark cutting. The modeling results are finally compared with compression tests performed on these simple architectured NiTi materials. As a further validation of the proposed study, two large cell structures (square and hexagonal stacking) were modeled to gain greater insight into the role of different architectures

This research related to the development of ultrasmall inner spiral ribbed copper tubes (ISRCTs) which have high quality and efficiency in transferring heat. The deformation behaviour of the ISRCT was studied. Three-dimensional finite element models were constructed for the various process parameters: the change of the cross-section profiles of the ribbed contours and the spiral angle of the ribbed area of the ISRCT, for twelve multi-pass drawings through the die using the tube sinking method. The effect of the ribbed spiral angle and the ribbed cross-sectional profile was also studied. Modelling and simulation techniques were performed using commercial Abaqus software to learn whether the surface profiles of the ISRCT increased or reduced with tube sinking using the finite element method (FEM). Results of the multi-pass drawing analysis were summarised and compared to the experimental findings. The FEM simulation approach was used to analyse the changes of ten parameters: von Mises stress, wall thickness, ribbed base width, ribbed tip width, ribbed base gap, ribbed tip gap, ribbed height, ribbed pitch, axial displacement and ribbed spiral angle. This procedure can be used to improve product quality and to study the effect of the various parameters. The results will be very valuable for researchers and well engineers for future design of ultra-small ISRCT to improve the quality and efficiency of heat transfer.

“…Bui et al (2011) determined the drawing limit of AA6063 tube using a 5°halfangle conical mandrel. The same approach using a 0.053°half-angle conical mandrel was applied for L605 cobalt-chromium tubes (Linardon et al, 2014). In her PhD dissertation, Linardon (2014) performed similar measurements on 316 LVM tubes and found a section reduction at fracture of 62.9%.…”

Tube drawing with a fixed plug is investigated experimentally and numerically in order to optimise an industrial pass sequence. Tube drawings are performed on a laboratory drawing bench equipped with force, displacement and temperature sensors. The drawing limit of 316 LVM stainless steel (SS) tubes is determined by varying the plug position and the effect of lubricant is discussed. The numerical model relies on the precise die geometry measured using a contact method and on the mechanical behaviour of SS 316 LVM characterised by tensile tests between 20°C and 200°C on annealed tubes. The friction coefficients between tube and die and tube and plug are determined by FE modelling by comparing measured and simulated plug, die and drawing forces. The use of a solid lubricant together with the lubricating oil prevents stick and slip and lowers the friction coefficients. Friction is further decreased by preheating the die. The identified friction coefficients are discussed in terms of the classic Stribeck friction curves and lubrication is found to be in the hydrodynamic regime.
