This sheet metal bending simulation depicts, a method to reduce Spring back is shown. The front cross section of the punch is rectangular in shape. The bend produced after this type of bending process forms a u shape that’s why also called U – bending. The sheet taken here is of 1mm in thickness. Punch velocity in downward direction is 3 mm/s. The variation of the punch force required is shown in the graph on the right side. The maximum punch force is 0.4 tonnes. The colored strip on the left side shows the different values of equivalent strain produced.
