  • Publication number: 20060137466
    Abstract: Instrumentation for monitoring crack growth using a change in electric potential across a starter crack as the crack propagates is disclosed. The instrumentation includes a specimen of a material to be analyzed for crack growth propagation having a surface with a starter crack formed therein, a plurality of current leads to pass electric current through the specimen, a layer of insulating material disposed on each of opposite sides of the crack, a layer of conductive material disposed on each layer of insulating material, where a portion of each layer of conductive material is in electrical contact with the first specimen surface, and a pair of sensing leads, one sensing lead attached to each layer of conductive material. A method for using the instrumentation to monitor crack growth by measuring is also disclosed.

  • Publication number: 20050193831
    Abstract: A test method for testing the thermal mechanical fatigue performance of a test material includes preparing a test specimen of the test material, wherein the test specimen has a base, and a rib extending outwardly from the base. The test specimen is thermally cycled through at least one test cycle. In each test cycle the rib is heated to a higher rib temperature and thereafter cooled to a lower rib temperature. The test specimen is evaluated for thermal mechanical fatigue damage.
