| Abstract Scope |
A common way of assessing the forming potential of sheet metals is a plot of strength vs. elongation, from uniaxial tension. Modern steels and aluminum alloys offer increasingly high strength, which comes with a reduction in elongation. This is taken to imply a reduction in forming potential over more conventional grades. Here, we examine this in terms of deep-drawability. We establish the drawing envelope of a simple material (pure aluminum AA1100) in two tempers: -O and -H24. The former exhibits significant work-hardening, and 26% uniform elongation (UE). The latter is almost perfectly plastic, with UE of 6%. The drawing envelopes of the two tempers are determined using cylindrical cup-drawing. The two tempers have the same Limit Draw Ratio and very similar drawing envelopes, despite their significant differences in uniaxial tension. A unified finite element model, that can capture both failure models (tearing and wrinkling) very well is also described. |
