... was accumulated. We are also using the data in our studies to incorporate damage parameters into popular constitutive models for solder such as the Norton and Garofalo creep models, and the Anand viscoplastic model.

... mechanics models and fatigue criteria for lead free solders that are subjected to variable temperature applications. KEYWORDS SAC305 Lead-Free Solder, Cyclic Stress-Strain Curve, Creep Response, Hysteresis. INTRODUCTION Solder alloys are used as interconnecting materials in modern electronic packages...

.... These samples were then mechanically cycled for various durations at testing temperatures of 100 °C. The measured cyclic stress-strain curves were used to characterize the evolution of the hysteresis loop properties (peak stress, hysteresis loop area, and plastic strain range) with high temperature mechanical...

.... Samples were cyclically loaded under both strain control (constant positive and negative strain limits) and stress control (constant positive and negative stress limits). The hysteresis loop size (area) was calculated from the measured cyclic stress-strain curves for a given solder alloy and temperature...
