Abstract

The problem of determining the design characteristics of structural metallic materials in connection with the new edition of Aviation Rules is considered. It is shown that the requirements for accounting for the influence of corrosion environments are included in the section laying down the requirements for the design values of strength properties. The criterion of damage to corrosion, which allows to realize the effect of «compression» of time, which provides the basis for the determination of the calculated values of the fatigue life when exposed to corrosive environment, is proposed. A list of the strength characteristics for which it is advisable to determine the estimated value of the strength characteristics of the humidity is established.
