  • Abstract
    A unified creep-plasticity model with damage is introduced and employed to simulate the isothermal cyclic behavior of Sn-Ag solder. The proposed damage evolution law is based on a nonlinear accumulation of damage and an interaction between applied load and creep. The stress drop amplitude and hysteresis loops are modeled over a wide range of loading conditions
