First, this is the wrong newsgroup. This group is for messages about 
programming, specifically the POV-Ray source code. Try povray.newusers, 
povray.advanced-users. Also, read the messages in 
povray.announce.frequently-asked-questions, especially "Welcome To the 
POV-Ray News Groups" by Ken Tyler. I am following up to 
povray.advanced-users.

About your question: are you talking about the sheet metal material that 
is cut and then stretched open? I think your best bet would be either a 
blob object or an isosurface. You might be able to get a reasonable 
approximation of this shape by using cylinderical blob components. As 
for the isosurface, it shouldn't be too difficult to make a function 
that looks something like this shape, but it will require MegaPOV, an 
unofficial "patched" version with many new features.

You also might be able to get something with an automatically generated 
mesh, though I wouldn't want to try coding that...

If detail isn't very important, you could probably do it with a 
partially transparent texture...
