I need to calculate delfection on a plate 36 X 46" under normal vaccum pressure. The only thing is there are 4 flanges around this plate which does not allow me to place a stiffner across it. I know that flanges after being welded in created stiffness but i cannot seem to find anything that will...
It was more difficult than that. here is the equation that works out
____________”thick plate __________#of stiffeners ___________” per stiffener
Ap = cross sectional area of plate within distance b
As = cross sectional area of stiffeners
B = distance between stiffeners
D = distance...
