Keywords: optimization, panel structure
The optimum design problem is one of the
inverse tasks, that means the structure
parameters are calculated according to a
known criteria of the selection, mathematically
described as a cost function.
The factor determining the development of
optimum design besides the hardware
equipment is the developing of the new methods
and new mathematical programming
algorithms. The optimum design of a skin
stringer panel using the method of non-linear
programming of Himelblaua [2] is presented in
this paper.
The cost function is the mass of the panel.
The constrains has to be chosen so that our
panel should satisfied the requirements for local
and global panel buckling, local and global
stringer buckling and it should satisfy as well as
the static resistance demands.
