The aforementioned analysis [6] may not be appropriate for such materials, since the weaker outer layer will evidently reyield in compression when sheet tension is removed.
The analysis examined the behaviour of single and double sided clad materials, highlighting the unique springback characteristics of each.
The results presented here indicate that accurate models of springback for Alclad aluminium require information on the residual stresses and the strengths of the core and clad materials.
