Hi, sooraj can you please explain the geometry or simply what your physical problem statement is?

Sooraj Sunil

when i done the bending of sheet metal, i have found wrinkles in the sheet. so i just want find the wrinkles corresponding to the bending radius or bending.

Thanks sooraj, .. I just have one question when you unbend sheet metal have you seen wrinkle disappears or some permanent deformation...?

go through the above link hope it help you going closer to your solution.. and when you start model your choose 3-dimensional S4R (shell) element.

Thanks again!
