ABSTRACT:
A method and apparatus are provided for detecting strain, stress, fatigue and incipient failure in materials. A detector (e.g., a photomultiplier tube) is used to detect photonic emissions from a material under test. Data based on the detected photonic emissions is displayed in real time so as to enable real time analysis of the data in determining strain, stress, fatigue and/or incipient failure.
