The Application of Infrared Microscopy in the Study of Polymer Fatigue.

Abstract

A model describing the frequency sensitivity of fatigue crack propagation (FCP) of polymers in terms of localized versus generalized specimen heating is examined. The magnitude of heating at the crack tip and across the unbroken ligament of the specimen is measured with an infrared microscope. The results confirm the earlier hypothesis regarding the observed frequency dependence of FCP behavior. (Author)
