Optimal design of rotationally symmetric shells for buckling under thermal loadings

Michał Życzkowski, Jacek Krużelecki, Piotr Trzeciak
In the present paper the problem of optimal design of a rotationally symmetric shell with immovable supports loaded by a uniform elevated temperature is investigated. We look for the variable thickness and the shape of the middle surface which lead to the maximal increment of the temperature causing buckling of the wall of this shell. The concept of the shell of uniform stability is applied.
