Abstract

A unified creep plasticity (UCP) model for Sn-Pb solder is developed in this paper. Stephens and Frear [1] studied the creep behavior of near-eutectic 60Sn-40Pb solder subjected to low strain rates and found that the inelastic (creep and plastic) strain rate could be accurately described using a hyperbolic Sine function of the applied effective stress. A recently developed high-rate servo-hydraulic method was employed to characterize the temperature and strain-rate dependent stress-strain behavior of eutectic Sn-Pb solder over a wide range of strain rates (10-4 to 102 per second) and temperatures (-60°C to +100°C). The steady-state, inelastic strain rate data from these latest experiments were also accurately captured by the hyperbolic Sine function developed by Stephens and Frear [1]. Thus, this equation was used as the basis for the UCP model for Sn-Pb solder developed in this paper. Copyright © 2010 MS&T'10®.
