Multilayer composites have recently attracted considerable attention due to their ability take advantage of the benefits various metallic materials simultaneously. The present study is first use parallel tubular channel angular pressing (PTCAP) as a severe plastic deformation method fabricate bimetal Al/Mg tube. This process was applied on commercially pure aluminum along with an AM60 magnesium...

During robotic assembly of flexible payloads, gravity and inertial forces acting on these payloads may induce both static shape deformation and vibration of the thin-walled payloads. Static deformations, which arise from deformation of the part due to its own weight under the influence of gravity, lead to misalignment of mating points of the part. Unwanted vibrations, arising from inertial forc...

 Thin-walled energy absorbers are used to reduce accident induced damages. In this study, thin-walled stainless steel structures in quasi-hemisphere geometry were subjected under quasi-static loading with Santam 150KN apparatus. Experimental results were compared with results of numerical simulations by LS-DYNA and it was shown that there is a good agreement between experimental and numerical r...

The residual stresses of the thin-walled injection molding are investigated in this study. It was realized that the behavior of residual stresses in injection molding parts was affected by different process conditions such as melt temperature, mold temperature, packing pressure and filling time. The layer removal method was used to measure the residual stresses at a thin-walled test sample by a...

Abstract To improve the crashworthiness and energy absorption of thin-walled tube structures, a bionic was designed based on structural characteristics antler osteon principle bionics had same inner outer diameters gradient thickness as osteon. A nonlinear finite element method is used to simulate with equal variation (EGTTS) under axial oblique loads. The EGTTS-7 (Egtts 7 layers) evaluated usi...
