Abstract

Fatigue fracture usually is defined as the failure of a part at a stress below its breaking stress due to repetitive loading conditions. It is now a well known fact that a part, designed for a maximum stress well below the yield point of the material, may be very apt to fail under cyclic loading conditions over a period of time. The metal appears to "wear out" after a time just like humans do and fatigue failure occurs. Metal fatigue may be contrasted to animal fatigue in that l) its detection before the latter stages is normally difficult if not impossible, 2) the condition is not dissipated by recovery, and 3) damage is cumulative.
