N2 - Magnesium alloys have low elongation at room temperature. Warm forming is a common method used for forming of magnesium alloy sheets. In the V-bending process, the bending deformation of magnesium alloy sheet due to effect of strain rate is different at the room temperature and 250°C. The bending behaviour at 250°C makes the radius of curvature of sheet larger than the punch radius. The results of V-bending deformation of magnesium alloy sheet in warm forming were investigated both experimentally and numerically. Three-point contact occurred due to effect of strain rate at 250°C.
