Direct Current Potential Drop (DCPD) Solution

Direct Current Potential Drop (DCPD) measures the change in resistance of a specimen, which correlates directly with crack growth. It is an effective way to collect fatigue crack growth data in high-temperature tests and other challenging environments. DCPD is used to overcome the challenges that make contact extensometry and compliance calculations impractical for crack length measurement.
