In the estimation of the fatigue life of lead-free solder joints under cyclic temperature load, it is important to use FE analysis technology using a constitutive model which can exhibit mechanical properties of the lead-free solder joints. In previous study, we proposed a decoupled viscoplastic-creep constitutive model which can describe stress strain curves, stress strain hysteresis loops and stress relaxation curves, with these temperature dependencies and these rate dependencies. In this study, the algorithm for stress calculation is built by implicitly-time-integration scheme to our proposed model, aiming at improvement of stability. Next, the algorithm was implemented into finite element analysis code ABAQUS via its user material subroutine UMAT. Then, tensile tests, tension-compression tests and stress relaxation tests were analyzed, using this program. It was confirmed that the stability of the analysis was improved.
