Research on sheet-metal flexible-die forming using a magnetorheological fluid

- A new flexible-die forming method for sheet metal based on magnetorheological (MR) fluids, magnetorheological pressure forming (MRPF), is proposed.
- Magnetorheological pressure bulging tests of Al1060 sheet under different conditions are conducted on the self-designed experimental apparatus.
- Effect of MR fluid's rheological behavior under different magnetic fields, especially viscosity, on sheet's formability is evaluated.
