WebOct 1, 2024 · Conclusions. In this work, we demonstrate a fatigue-resistant elastomer made from commercially available Spandex fibers and PU matrix, through a fiber–matrix composite design. The obtained composite shows a large stretchability of 6.0, toughness of 16.7 kJ/m 2, and fatigue threshold of 3900 J/m 2. WebMar 1, 2024 · In the present experimental work, the behavior of AISI H11 and AISI H13 tool steels will be studied by tensile and strain controlled low cycle fatigue tests at different temperatures: 20 °C, 200 °C, 350 °C and 550 °C. The cyclic tests will be performed in tension and in compression at four strain levels, i.e. 0.4%, 0.6%, 0.8% and 1% [10], [11].
