Timoshenko - Theory of Plates & Shells 1

[pperlich]

2nd Edition, Chapter 1, Article 1 the following statement is made and is key to the solution: "The lateral strain in the y direction must be zero in order to maintain continuity in the plate during bending..."

I don't grasp that concept. It seems to me like there could be a small amount of strain in the y direction, and rather than a loss of continuity, the cross section of the plate would end up as a trapezoid.

What am I missing?

Thanks in advance!

Since Timoshenko was Russian, much of his work was translated which seems to give testimony to Bridgwater's statement " A little off topic but this thread calls attention to a typo in the book."
