摘要

在75℃恒温条件下，用不同方法对SnAg3.5合金进行了疲劳试验比较。采用恒应变速率为±1e - 31 1/s的循环恒速率实验确定Coffin-Manson参数。此外，通过联合松弛实验和恒力实验，还比较了恒速率与慢应变速率的行为。

Study of constant rate and constant force low cycle fatigue methods for solder characterization

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.
