Flat Plate Natural Frequency Calculator

Rating:

Description


“a” and “b”, the dimensions of the plate
“c” and “d”, the half-dimensions of the plate (for polynomial equations)
“E”, plate material Young’s modulus
“h”, the plate thickness/height
“μ”, plate material Poisson’s Ratio
“γ” or “ “D”, plate stiffness factor (defined on References sheet)
“Z”, plate deflection at resonance

Dear Author of ExcelCalcs,
You have a very nice program which I am using for determining the natural frequency of flat plates. Questions 1 - 4 have been answered by John Doyle, however I'm curious about responses to questions 5, 6 and 7 below and would appreciate guidance from you on these points.
5. What is the meaning of a1, a2, b1, b2, c and d? Do a1, a2, b1 and b2 signify the dimensions of a generalized polygon with different dimensions a1, a2, b1 and b2?

6. What is the meaning of “c” and “d”? They appear to the be midpoints in both dimensions of the plate, but I’d like to verify this interpretation.

7. If a1, a2, b1 and b2 are dimensions of a polygon having different dimensions for all 4 sides, then how are these 4 values inputted into the Plate Frequency Calculator in cells B5:6?

Thank you in advance,
