    Large Deflexion analysis won't converge

    Thanks for your response. To be honest we normally assume that buckling has occurred when the iterations don't converge but in this case we can't see how the plate can buckle. It is restrained all round its perimeter and we are only applying an out of plane load so the plate should be in...

    Large Deflexion analysis won't converge

    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...
