“…In order to achieve a suitable joint, Haynes et al [27,28] and Oikawa et al [29] found that the thickness of the aluminum cladding should be 40% to 60% of the total thickness of the bimetallic sheet. An example of this welding method is shown in Figure 6.…”

Hybrid car bodies fabricated by joining parts made with steel and aluminum alloys are becoming increasingly common. This provides an affordable mean to decrease the car weight by using lighter or more advanced materials only where they can achieve the maximum benefit. This development is driven mainly by recent regulations on carbon dioxide emissions, and hinges on the deployment of effective joining technologies. In most cases, such technologies were not previously used in the car sector, and must be adapted to its requirements. Several dissimilar welding technologies, based on either fusion welding or solid-state welding, are reviewed here, focusing on dissimilar joining among steels and wrought aluminum alloys. These technologies are either presently being introduced in the car industry, or are used in other sectors and could be applied in the car industry in the near future.

“…The automotive industries worldwide are facing several challenges like improving energy efficiency, reducing emissions, enhancing safety and appeal at reduced cost 1 Material scientists, automotive experts and application engineers work together to address these tough challenges by offering lightweight, cost-effective multi-layered material technology solutions which are difficult to achieve by using conventional sheet metal applications. [1][2][3] Design and development of the clad composite material involve stacking of two or more layers of different thicknesses and materials of the same or different grades to produce a composite clad sheet metal with desired engineering properties. 4 These clad metal systems may incorporate a range of combination of sheet materials like ferritic stainless steel, austenitic stainless steel, copper alloys, aluminium alloys, magnesium alloys, titanium alloys etc.…”

In the present work, springback behaviour of a three-ply clad sheet metal, comprising of layers of SS430 and SS304 sandwiched with a layer of AA1050 is investigated in V-bending by using analytical, experimental and simulation techniques. The developed analytical model is based on theory of bending using Hill’s anisotropic yield criterion. The tensile properties of the clad sheet and individual layers oriented at three different directions w.r.t. the rolling direction are characterized. The tensile properties of the individual layers are used in the material model of analytical and numerical predictions of the springback. It is observed that the samples of the clad sheet which are transverse to the rolling direction, exhibit highest springback values due to higher tensile strength of the sheet when compared with the results acquired for other two orientations w.r.t. the rolling direction. These results are endorsed by the springback results obtained from analytical and simulation methods. The effect of sheet setting on the die during bending is also investigated using different techniques. The resulting longitudinal stresses before and after springback are analysed on inner and outer layers of the tested samples using experimental and numerical simulation procedures. In both the cases of sheet settings, the results of residual stress after springback predicted by simulations agree with the experimental results except a few cases.
