Fatigue tests were performed under load control mode on a Schenck horizontal fatigue testing machine with hydraulic grips and a maximum load capacity of 25 kN. Tension-tension constant amplitude fatigue tests were carried out at three stress levels 60% a , 70% Cu and 80% a at two different stress ratios R = 0.1 and R = 0.5. The test frequency was kept constant (f = 3 Hz) for all the tests. [Pg.46]

The cord fatigue phenomenon and effect of twist has been discussed (61). Values of Young s modulus of some belt and carcass cords used in passenger tires are given in Table 4 (62). Poisson s ratio of tire cords is often in excess of 0.5 due to twist the higher the twist, the larger Poisson s ratio of cords. [Pg.86]
