Optimal design of minimum mass structures for a generalized Sturm-Liouville problem on an interval and a metric graph
We derive an optimal design of a structure that is described by a Sturm-Liouville problem with boundary conditions that contain the spectral parameter linearly. In terms of Mechanics, we determine necessary conditions for a minimum-mass design with the specified natural frequency for a rod of no...

| Summary: | We derive an optimal design of a structure that is described by a
Sturm-Liouville problem with boundary conditions that contain the
spectral parameter linearly. In terms of Mechanics, we determine necessary
conditions for a minimum-mass design with the specified natural frequency
for a rod of non-constant cross-section and density subject to the boundary
conditions in which the frequency (squared) occurs linearly. By virtue of
the generality in which the problem is considered other applications are
possible. We also consider a similar optimization problem on a complete
bipartite metric graph including the limiting case when the number of
leafs is increasing indefinitely. |
