Fatigue lifetimes of lead-low tin solders have been investigated. Results indicate that the Coffin-Manson law does not fit the experimental data. The phenomenon correlates with a change in failure mode of transgranular and mixed for higher strain ranges, and intergranular at lower strains. The modeling incorporates the appropriate micromechanical features, and in addition shows that the variation in the failure mode and in the magnitude of the stresses from varying strain range (during the cyclic process) coincide with each other.
