To demonstrate the versatility and applicability of the techniques developed, two simple systems of beam-beam and plate-beam type structures are investigated.
Since, especially for higher frequencies, Timoshenko's theory gives more reliable results than Euler Bernoulli's theory, systems of beams, like frames, under arbitrary dynamic excitations should be analyzed on the basis of this refined theory.
In the measurement system of beam quality factor, M2, wave-front and intensity aberrations caused by optical elements, thermal effects, residual pump light, etc., influence the measurement results.
A nonlinear model for a vibrating Timoshenko beam in non-forced unknown rotation is derived from the virtual work principle applied to a system of beam with mass at the end.
The performance of the system consisting of beam structures is very much affected by identification of faults or damage in it's structural integrity.

Though it will hardly be much to look at, it will be outfitted with the latest in trial technology: a computerized system for digital document display; wiring for hidden translators working in as many as five languages; and a 10-camera automated system to beam video of the proceedings to a press center in an aging aircraft hangar nearby.
The latter approach was developed based on the theory of structures to address to systems of composite beams.
The result, which retains the accuracy of the elemental Green's functions, isexactfor systems of Euler Bernoulli beams.
An established approach for doing this is based on the assumption that discrete systems of spandrel beams connecting the columns may be replaced by a continuum model of equivalent stiffness.
