Unified viscoplastic constitutive model for Sn3.8Ag0.7Cu solder


The time-independent plastic and time-dependent creep deformations of Sn3.8Ag0.7Cu solder are considered in a unified framework by using a state variable approach. A new viscoplastic constitutive model that includes the kinematic hardening behavior of solder is proposed in this paper. Back stress, which is used for characterizing the kinematic hardening… (More)
