  • Asphalt Crack Detection Using Thermography
    , white cracks, and a variety of other problems have presented serious challenges to automated crack identification and detection in this frequency region. The goal here is to test the hypothesis that asphalt cracks cause changes to surface conditions and emissivity leading to perceived temperature
  • Choosing The Right Force Sensor for Aerospace Testing
    of the repetitive, reverse loading. It is generally acknowledged that a structural fatigue failure develops in three stages: 1. Repeated cycling builds up local plastic deformation, and a microscopic crack is initiated. 2. The crack propagates and a larger section becomes weakened. 3. Stress
  • Sensors help gauge if jets are fit to fly
    As aircraft reach or exceed their planned life spans, the U.S. Air Force is turning to advanced nondestructive evaluation methods to decide whether the planes are fit for continued service. A low-profile magnetostrictive sensor detected a crack and monitored its growth on an A-10 aircraft test

    it. The patch has laseretched rows of tiny, interconnected channels or galleries, to which a vacuum is applied. Any propagating crack under the sensor breaches the galleries with a corresponding change in pressure. The CVM sensors provide equal or better sensitivity than conventional inspection methods
