EFFECT OF TRANSIENT PHENOMENA ON STRUCTURAL MATERIALS OF POWER SYSTEMS

Abstract

Untimely failure of structural materials of the electric energy industry may often be attributed to low-cycle fatigue effects. Presentation of the stress background of these effects is followed by that of some typicai damage statistics and damage examples. Low-cycle fatigue tests arc likely to yield valuable information. The mechanism of material structure damages in low-cycle fatigue has been outlined, together with prevention possibilities. Further increase of the breakdown safety of our power system, reduction of the number of so-called unexpected outfalls reducible to material damages require to grasp any possibility to reduce or prevent adversities of transient effects on the material structure.
