Error in Theory of Plates and Shells by Timoshenko 1

[Hokie93]

For those who use Theory of Plates and Shells by Timoshenko, an error in Table 47 of the second edition has been discovered. The error is discussed in an article by Angus Ramsay and Edward Maunder in the July 2016 issue of STRUCTURE magazine (

http://www.STRUCTUREMag.org).

The error seems to be typographical in nature. For an aspect ratio (b/a) equal to 0.5 and at the center of the plate, the M_y coefficient (β₁') should be 0.0120, not 0.0102.

Furthermore, this same topic was presented recently in the IStructE publication The Structural Engineer.

Article attached.

If that is the only error in the book, that would be a remarkable achievement.

That it has taken so long to find it is not quite so remarkable.

I wonder how many other publications that number has found its way into.

Dang. That just invalidated my life's work.

NAFEMS also did a benchmark problem that lead into the presentation of this error:
