Abstract :
Low cycle isothermal mechanical fatigue testing of a eutectic alloy
63Sn/37Pb was carried out in a systematic manner over a wide range
of frequencies (10 minus 4 minus 1 Hz) and temperatures ( minus 40
to 150 degree C) with the total strain set at different values
(1-50%).The low cycle fatigue behavior of the eutectic solder was
found to be strongly dependent on test temperature and frequency. If
the Coffin-Manson model is used to describe such fatigue behavior,
the fatigue exponent m and ductility coefficient C in the model are
found to be a function of temperature and frequency rather than
numerical constants.The plastic flow law was employed to explain the
temperature and frequency dependence.The frequency-modified
Coffin-Manson model was tried and found to be able to eliminate the
frequency dependence of the numerical `constants' but not the
temperature dependence.To have a full description of the
temperature- and frequency-dependent fatigue behavior, a set of
empirical formulae was derived based on the frequency-modified
Coffin-Manson model.(Author abstract)
