I want to deform a shell structure into a flat shape and then read the stress it experienced on the surface.

I tried this with some simple objects like halfpipes and with different methods, but it does not always work. I tried pulling it, but that only works for cylindrical objects, and crushing it on to a plate results in errors after some deformation.

I was hoping to get some input on how to do such a simulation with Ansys or an idea how to do this better. I am thankfull for any help.

 

It is not supposed to be a simulation of a real process, I just want to know, which parts of the geometry deform the most when forcing a 3D-shell to a flat state (or vice versa).

HI

I would suggest to use explicit dynamics for this (static can not solve this).

See here for a tutorial:

I cant get any solutions with explicit dynamics. This seems to be a common problem.
