Hi Brian,
It has been stated in the past, that above 100C near-eutectic solder creep
flow can be described using the Navier Stokes equation; I do not know on what
experimental evidence this statement is based, however.
I like to hear more about your "viscous flow model for low cycle fatigue."
How will you quantify the cyclic damage, and how will you relate this to
cycles-to-failure (however you define failure).
