Difference between Sheet metal and Extrusion simulation

I have done a simulation using approximatley a 90 degree bend in it. I was having issues with the sheet metal feature so I decided to make it as an extrusion first. I then ran a simulation with incremented amounts of force and collected the results. Recently I re-ran the simulation after getting the sheet metal feature figured out. Using the same material and the same shape of a part, The resulting peak stress in the part was less than half of the peak of the extruded part. Can anyone help me in explaining why?
