Hi emil,
The thing is that like wlw32 I'm looking at concentrated loads or loads applied in small circular/rectangular regions on the middle of the steel membrane.
These loads produce large deflections. So far I've been at a loss in trying to track down theoretical sources that can provide...
I am looking into the same situation - concentrated loads on membranes (stainless steel, 1000mm x 2000mm x 1.5mm).
I'm looking for approximate solutions at this stadge, so does Wang & Salmon's text provide some approx. formulae for different cases of conc. loading?
Or would one have no choice...
