Deflection of simply supported equilateral triangular plate The plate rests on a frame in the form of an equilateral triangle. The triangular part of the plate is loaded uniformly distributed load. The equation of the surface of deflections of a triangular plate is taken from the book of S.P.Timoshenko.Timoshenko S.P., Woinowsky-Krieger S. Theory of plates and shells. New York, NY: McGraw-Hill; 1959. triangular plate.sm (13kb) downloaded 72 time(s).Edited by user 19 April 2022 18:12:24(UTC)

Thanks Ber7 for that one and the other one few days ago.

On my own, I published several times more than the entire Mathcad Community. I don't miss them in Smath 6179, why ? purely useless for the Engineer. They are just for the Gallery [Tom G. would say Peanut Gallery]. We are just waiting for a stable Smath version delivered with Maxima plugin and more of the possible plugins. Scilab looks far superior to Maxima ?

Hello Beer7, is this vibration of a rectangular membrane equivalent to the deflection of a simply supported, uniformly loaded, rectangular plate? (leaving aside the physical parameters like plate thickness, Young's modulus etc.) I am only interested in the curvature on various locations on the surface, not in absolute values (max deflection can be calculated using simple civil engineering formulaes). Thanks, Laurent Originally Posted by: Ber7
