✦ Synopsis

Temperature and frequency effects on fatigue crack growth rate have been modelled. The "stress intensity factor"-biased Arrhenius equation and a result from the "two-stage zone" model have been incorporated into the present model. Subsequently, temperature and frequency effects on fatigue crack growth in unplasticized polyvinyl chloride (uPVC) were studied over a temperature range 15-55~ and a frequency range 0.01-10 Hz. Data for PVC taken from the literature were also included for analysis. It was found that the 3redicted values from the proposed model are in good agreement with experimental results.

Fatigue crack growth (FCG) in a commercial-grade acrylonitrile-butadiene-styrene (ABS) over the temperature and frequency ranges of 10-70Β°C and 0.01-10 Hz was studied. A model for the effects of temperature and frequency on the FCG rate was refined. The refined model is shown to accurately predict F

A detailed study on a silicon nitride reinforced with silicon carbide whiskers has been undertaken on room temperature fatigue during static and dynamic loading at constant DK. It is shown that sub-critical crack growth rates are lower when the material experiences sustained far field loading than d
