Moebius strip bending stress analysis - any ideas?

Hey all,

I would like to be able to calculate the internal stress of a Moebius strip that results form the bending of the flat sheet of material.

I know there are several discussions on stress analysis on this forum, but I only found cases where the stresses are resulted from applying forcees on a shape, not as a result of warping and twisting a shape into a certain confuguration so i am hoping someone here can help.

Many thanks for your interest!
