Normally when a sheet metal is subjected to bending, everyone have a clear picture in mind how it progresses. But, i am having a problem concerning the same, i.e., when i subject the sheet metal to bending, it bends but with one unusual behavior, it is behaving like a rubber sheet or that it is getting deformed in an unacceptable manner.
Is it the problem with the material properties (which i am listing out here in the picture) or something to do with the amplitude (i used smooth step) or something else.
