Series: ASM Failure Analysis Case Histories
Volume: 2
Publisher: ASM International
Published: 01 December 1993

...Abstract Abstract A helicopter tail rotor blade spar failed in fatigue, allowing the blade to separate during flight. The 2014-T652 aluminum alloy blade had a hollow spar shank filled with lead wool ballast and a thermoset polymeric seal. A corrosion pit was present at the origin of the fatigue...

.... In this classification, wear study is separated as elastomers, thermosets, glassy thermoplastics, and semicrystalline thermoplastics. The article describes the effects of environment and lubricant on the wear failures of polymers. It presents a case study on nylon as a tribological material. The article explains...

This article briefly reviews the mechanical behavior and fracture characteristics that discriminate structural polymers from metals. One of the most important differences between polymers and other materials...

This temperature, in turn, depends on the average molecular weight of a thermoplastic polymer or the degree of crosslinking for a thermoset polymer. Polymers used above their T g can readily creep under...
