Claim 8:
9. A system for testing a structural integrity of a metal joint, comprising:
a stimulus device configured to stress the metal joint;
a resistance measuring device configured to measure a resistance of the metal joint while the metal joint is stressed by the stimulus device, wherein the resistance is measured using a four-terminal (4T) sensing method by separate pairs of current-carrying electrodes and voltage-sensing electrodes; and
a test automation platform, comprising a memory that stores executable instructions, and a processor configured to execute the instructions retrieved from the memory, wherein the instructions, when executed, cause the processor to determine a structural integrity of the metal joint based on a comparison between the measured resistance and a baseline resistance, wherein: the resistance measuring device is configured to measure a complex impedance of the metal joint while the metal joint is under stress; and the instructions, when executed by the processor, cause the processor to determine a difference between a real component of the measured impedance and the baseline resistance.
