Abstract :
This paper presents a comparison of fatigue experiments with the SnAg3.5 alloy tested with different methods under a constant temperature of 75°C. Cyclic constant rate experiments with constant strain rates of ±1E-3 1/s were used to determine Coffin-Manson parameters. Furthermore the constant rate behaviour was also compared with slower strain rates, with combined relaxation experiments and constant force experiments.
