Résumé: The study is devoted to investigation of stability loss of a thin-walled rectangular elongated plate, subjected to simultaneous action of permanent longitudinal compressive forces and uniform surface corrosion. The plate is considered as a thin elastic isotropic body with simply supported butt ends on the long side. Subcritical stress state in the plate is described within Kirchhoff-Love approximation and it is membrane- like. The critical time of stability loss of the plate is found. It is shown that the critical time can be established if the solution of the respective problem of the static stability loss for the plate, not subjected to corrosion, and law of corrosion rate are known. Numerical results are received for plates, made from steel and aluminum, with different initial wall thickness.
