Main Question or Discussion Point

I want to calculate/preparing a spread sheet for large deflection of simple supported plates. I search for too many documents but all of them for small deflection d≤ t\2 (d deflection, t thickness of sheet). I found a web site http://www.xcalcs.com/cgi-bin/tutti/x3calcs.cgi?d=i_4_2_1_0_0&l=en but it is not clear how found coefficient in formulas. b/a etc.

Thanks in advance for cooperations

Large deflection theory for plates (or beams for that matter) is very complex mathematically.
