I'm looking for a reference with deflection solutions for simple loaded plate and shell elements. I'm trying to estimate the deflection of a disk that is supported at its OD and has an axial uniform load over its surface. Can someone provide some help or advise?

dgunther,
I think you want to look at Roark's Formulas for Stress and Strain to start.

dgunther,
From Machinery's Handbook for the situation you have described. Edge "supported" around circumference and a uniform distributed load over the surface of the plate:
d = 0.221 WxR^2/Et^3
(if the edge is fixed the multiplier changes to 0.0543)
Where -
d = deflection in mm
W = load in N
R = Radius of plate to supported edge mm
E = modulus of elasticity in N/mm
t = thickmess of plate in mm
Hope this helps

gjb,
If the disc has an hole in it of radius R0, would the equation be:
d = 0.221 Wx(R1-R0)^2/Et^3
where R1 is the outer diameter, and R0 is the inner diameter?
Also are the units of modulus of elasticity in N/mm2 and not N/mm?
thanks for your help!

Hi I looked at that book, it didn't have the disk deflection equation.
I was thinking that this might be the deflection correct equation for a disc with a hole in it.
d = 0.221 Wx(R1^2-R0^2)/Et^3
where R1 is the outer diameter, and R0 is the inner hole diameter.
Any input would be appreciated greatly!

dgunther and dualspirasystems,
look in the site below under Plates -> Simple bending -> Annular pl. -> Supported-free -> Distr.load , hit Formulas, and you'll get perhaps more than what you are looking for.
