  • Nonlinear ultrasonic testing for non-destructive measurement of longitudinal thermal stresses in solids
    Patent number: 9989498
    Abstract: Methods and apparatus, including computer program products, are provided for nonlinear ultrasonic testing. In one aspect there is provided a method, which may include generating at least one ultrasonic wave to enable the at least one ultrasonic wave to propagate through a solid; detecting the at least one ultrasonic wave propagating through the solid; and determining a stress of the solid based on at least one of an imaginary component of a wavenumber, a wave amplitude, a wave strength, a statistical moment in a time domain, or a statistical moment in a frequency domain of the at least one ultrasonic wave.
    Type: Grant
    Filed: February 5, 2014
    Date of Patent: June 5, 2018
    Assignee: The Regents Of The University of California
    Inventors: Francesco Lanza di Scalea, Claudio Nucera
  • Stress detection in rail
    Patent number: 9689760
    Abstract: Methods and apparatus, including computer program products, are provided for determining rail stress. The method may include generating at least one ultrasonic guided wave to enable the at least one ultrasonic guided wave to propagate through a rail; detecting at least one of a fundamental frequency component of the at least one ultrasonic guided wave, one or more harmonics of the at least one ultrasonic guided wave, and/or a mixing component of the at least one ultrasonic guided wave; and determining a stress of the rail based on at least a nonlinearity parameter determined from the detected at least one of the fundamental frequency component, the one or more harmonics, and the mixing component. Related apparatus, systems, methods, and articles are also described.
