Operational Details of Crack Track System

The CrackTrack system works on the principles of potential drop in an electric circuit. The crack gage has an adhesive file on the back and can be easily mounted on the DCB specimen. The crack locator gage attaches to the component board via the ribbon cable and the adapter. A crack propagation beneath the gage induces local fracture of the sensing strands on the gage. The system box continually sends signals to the onboard computer on the test machine and at any given time the crack length and the location of crack is directly proportional to the voltage signal read by the test machine computer. The LEDs located on top of the system box in tracking the crack visually while the experiment is still in progress. The systems can be used on DCB specimens of varying thickness and length.
