Triangular plate stress calc.
Triangular plate stress calc.
(OP)
We need to calculate the max stress on a triangular plate used in our assemblies. The plate is an isosceles triangle welded on all 3 edges to fill a gap. It is subjected to 7 bar pressure. Can anyone suggest a suitable calculation to use so we can avoid FEAing it





RE: Triangular plate stress calc.
Roark's Formulas for Stress and Strain 7th ed.
TABLE 11.4 Formulas for flat plates with straight boundaries and constant thickness
Case No. 18: Right-angle isosceles triangle; all edges simply supported
18a: Uniform over entire plate
The equations are quite simple.
i.e. Sigma (max) = 0.262qa^2/t^2 where q is the load, a is the height of the triangle, t thickness.

Of course I suppose you know that welded does not necessarily imply fixed.
