  • Methods and systems for non-destructive estimation of a length of a member
    Patent number: 10451399
    Abstract: An example non-destructive method for estimating a length of a member, which may be embedded, is described herein. The method can include impacting the member, recording a respective signal at each of a plurality of sensors attached to the member, and transforming the respective signals into a frequency domain. The respective signals can include dispersive waves generated by the impact. The method can also include determining an effective wavenumber of dispersive wave propagation based on the respective frequency-domain signals, determining theoretical wavenumber of dispersive wave propagation using a dispersion relation for the member, and estimating the length of the member based on the relationship between the effective wavenumber of dispersive wave propagation and theoretical wavenumber of dispersive wave propagation.
