Calibration of a Constitutive Model from Tension and Nanoindentation for Lead-Free Solder.
TL;DR: A power-law model is adopted to describe the stress–strain relationship by means of analytical dimensionless analysis on the applied load-penetration depth responses from nanoindentation experiments, and two “rate factors” are proposed by multiplying the representative stress and stress exponent in the adopted analytical model.
