Non-Circular Vessel Design
Non-Circular Vessel Design
(OP)
hello,
I am looking for a method to design flat plates under low pressure and some accelerations. The shapes do not fall within the scope of App. 13 in SC 8-1. One shape has an elliptical cross-section, the other is hopper like with an inverted pyramid shape attached to the bottom of a cube shape. The pressures, materials, and inert nature of the contents do not justify the expense of FEA. Any suggestions on a reference? Or just sweat it out with Roark?
Thanks in advance

RE: Non-Circular Vessel Design
For example- on ellipse, perhaps consider checking as a circle with both the major and minor diameters, and figure you're results ought to be in between there. For a triangle, figure it ought to be stronger than a square with those dimensions. (assuming triangles and ellipses aren't in there, which they may be).
If you get someone really familiar with FEA, they could probably whip up a flat-plate design of arbitrary shape fairly quickly- about the easiest problem that could be done with FEA.

Otherwise I concur with the reference to Roark. If the budget does not allow for FEA, then it is also possible to adopt ample margins based onto a rough analysis, and be prepared to add some stiffeners after hydrotest.

Thank you both.
