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.

Optymalne kształtowanie powłok obrotowo symetrycznych z uwagi na stateczność pod działaniem obciążeń termicznych. W pracy rozważano zagadnienie optymalnego kształtowania obrotowo symetrycznej powłoki na nieprzesuwnych podporach obciążonej równomiernym polem temperatur. Poszukiwano takiej zmiennej grubości ścianki i kształtu powierzchni środkowej, które prowadzą do maksymalnej temperatury powodującej wyboczenie ścianki powłoki. Wykorzystano koncepcję powłoki równomiernej stateczności.
