Large Deflexion analysis won't converge
Large Deflexion analysis won't converge
(OP)
I'm trying to analyse a fairly simple flat plate under surface pressure (out of plane loading) using large deflexion theory. I have no problem down to a plate thickness of 2mm but as soon as I drop below about 1.6mm I get an error message saying that the iteration will not converge. I haven't given any value of yield strength, so the plate can't be actually failing. Now the maths shouln't care what thickness I use so I presume it is some sort of limit in a default setting. I have had a go at changing these but haven't got anywhere.
Has anyone got any ideas why I am having this trouble.
Thanks

Any suggestions would be welcome.

Have you tried altering numbers of iterations and any other available solution parameters?
Do the boundary conditions allow the plate to go into tension, when bending deflections get large?
