Stresses in triangular plate
Stresses in triangular plate
(OP)
Does anyone have references for calculating the stresses and the deflections in a simply supported triangular plate under uniform loading or pressure? My Roark's only has round and parallel edge supports. Thanks!!

I am using MathCAD's extension pack and it does not have this load case.

I'll be out of the office until late tomorrow afternoon. If I don't see anything posted by then I will try to get it scanned.

I have not been able to get a good scan off the equipment I have. If you still need it, maybe someone else can help.

Here is an excel based software named "Plate Analysis"
(based on "Roark's Formulas for Stress & Strain" 6th edition")which has all forms of plates & loadings as triangular well:

If you can, I would appreciate it very much. If not, I understand and thank you for your efforts to date.

Your demo only does rectangular supports, but thanks anyway!
RE: Stresses in triangular plate
for an equilateral triangle, simply supported sides, constant thickness, with a uniform pressure load
maximum stress = 0.207q*((L/t)^2)
where q = applied pressure
and L = side length
(the equation is in terms of a, the perpendicular height, = L*sqrt(3)/2)
and max displacement = -0.019q(1-nu^2)L/E*((L/t)^3)
nu = 0.3 ... (1-nu^2) = 0.91

I just sent two scans to the email address in your profile.
The quality is about the best I can do.
Hope it works.
