..., and their alloys. Although aluminum and magnesium alloys have great potential for producing sheet metal parts with reduced weight, these alloys have limited formability at room temperature and require special processing techniques. One way of improving the formability limits of these materials is to conduct...

... on active drawbeads shows that a controllable restraining force, caused by adjusting the penetration of drawbeads, can improve sheet metal formability ( Ref 15.6 ). Drawbead restraining forces, at a constant depth, increase with the flow strength of the sheet metal because bending deformation around...
