  • Method and apparatus for detection and characterization of mechanical damage
    Patent number: 8960012
    Abstract: Yield stress is an important indicator of the strength of a component such as a pipe section. A method and apparatus for measuring yield stress of components made from magnetic materials is provided. The magnetic permeability of the material is recorded at multiple stress levels below yield establishing a permeability-stress relationship. The yield stress is then estimated as a function of the recorded permeability-stress relationship. The permeability stress relationship may be non-linear for a range of stress levels, achieving a peak permeability response for a stress below yield. The yield stress may be estimated as a multiple of the stress at which the peak permeability response is recorded.
