Hi everyone.
I'm working on my master thesis, dynamic analysis of plates using finite strip method.
I have found one problem (among others) that could be interesting to community.
In the attachment you can find example from Mathematica. There is 21 mode shapes of clamped-clamped beam. Recently i noticed that formulation given in every book about dynamics (Timoshenko, for example) isn't valid for higher modes for any beam that isn't pinned on both ends.
