Abstract: In this paper we study the corrosion of the thin spherical shell containing and surrounded by corrosive media, generally of different corrosion coefficients. Two alternative corrosion models are studied. Optimisation study is also conducted with a view to determine the optimum thickness.

Keywords: double-sided corrosion; Dolinsky model; Gutman/Zainullin model; optimisation; durability; stress state.
