Combined creep and fatigue measurement method for lead-free solder alloys

Abstract

This work studies the secondary creep behaviour at approx. 25% stress drop in the fatigue curve on bulk solder specimens in a tensile and compression experiment. With the adaption of the pre-factor of the secondary creep models the acceleration is describable. To get a good correlation between the model as well as the real tensile and compression experiments, advanced modelling with primary and tertiary creep will be necessary.
