The Interpretation of Creep Failure in Textile Fibers as a Rate Process

Abstract

Some theoretical results are presented which have been obtained using an absolute reaction rate approach for discussing the time dependence of creep failure in textile fibers. The methods used permit a calculation of the functional form of the following relationships: (1) the dependence of the time required for breaking on the magnitude of a sustained dead load; (2) the dependence of the fatigue life under a noncompressive periodic load on the stress amplitude and frequency; (3) the dependence of the tensile strength on the rate of loading used in its measurement; (4) the dependence of the strength loss in a fatigue experiment on the time of exposure. The theory suggests that it may often be possible to predict the results of measurements of all of these quantities from the measurement of one of them. The conditions under which this is true are discussed in detail here.
