Abstract |
For a cantilever beam subjected to a retarded follower force, the increase
of the critical load by means of the material redistribution along the beam
length is considered. The influence of the time delay parameter
is studied in detail. It is shown that the optimization of a
non-conservatively loaded beam can result in substantial (up to
several times) increase in the critical load. For the optimized beams,
only the flutter instability is observed. As the system
non-conservativeness increases, the critical load multiplicity (i.e., the
number of coinciding local optima) for the optimal beam also
increases. |
