This paper treats the prediction of fatigue life of 60Sn-40Pb solder alloy using the plastic strain work density per unit time calculated from the proposed constitutive model for cyclic viscoplasticity. At first, in order to verify the applicability of the proposed constitutive model to the deformation of 60Sn-40Pb solder alloy, a series of basic experiments, such as creep tests and cyclic tension-compression loading tests are performed at 303K, 323K, 343K. Then, the proposed constitutive model is used to predict fatigue failure of the solder alloy. As a result, it is clarified that the proposed constitutive model is applicable to explain the viscous deformation of the solder alloy, and that its fatigue failure can be predicted using the plastic strain work density per unit time.
