“…Research into polymers' fatigue behaviour started with investigations on rubber, first studies being performed by Cadwell et al and Fielding in the 1940s. Recently, fatigue experiments on various types of polymers have been carried out with emphasis on fatigue life prediction using Wöhler experiments with materials such as polycarbonate or polyvinyl chloride as well as on crack growth, for instance, in rubber, acrylonitrile butadiene styrene, poly(methyl methacrylate) or polyether ether ketone …”

“…Research into polymers' fatigue behaviour started with investigations on rubber, 9 first studies being performed by Cadwell et al 10 and Fielding 11 in the 1940s. Recently, fatigue experiments on various types of polymers have been carried out with emphasis on fatigue life prediction using Wöhler experiments with materials such as polycarbonate 12 or polyvinyl chloride 13,14 as well as on crack growth, for instance, in rubber, 15 acrylonitrile butadiene styrene, 16,17 poly(methyl methacrylate) 17,18 or polyether ether ketone. 19 Low-cycle fatigue (LCF) tests were developed for investigating the fatigue behaviour of metals at relative high strain/stress levels as a way to replicate the in-service loading patterns of some components.…”

This work investigates a decrease in mechanical properties of a polyamide‐based polymer, previously subjected to low‐cycle fatigue tests in strain control. Variations in its tensile stress response under monotonic loading and instantaneous elastic modulus were studied in relation with three loading parameters of low‐cycle fatigue under strain control pre‐treatment, that is, number of cycles (5000, 10 000 and 50 000), frequency (3, 5 and 7 Hz) and reference strain (0.025, 0.035 and 0.045 mm mm−1; a constant amplitude of 0.0075 mm mm−1 was maintained). The tests (static and cyclic) were performed with a servo‐hydraulic testing machine Schenk PC63M equipped with a strain‐gauge extensometer. A significant softening in tensile stress response (32%) was observed after 1000 cycles with a decrease of 44% recorded after 50 000 cycles; the levels of frequency and the reference strain level within the test envelope have, instead, a small effect.
