Finite-size effects on the quasistatic displacement pulse in a solid specimen with quadratic nonlinearity

PB Nagy, J Qu, LJ Jacobs - The Journal of the Acoustical Society of …, 2013 - pubs.aip.org
There is an unresolved debate in the scientific community about the shape of the quasistatic
displacement pulse produced by nonlinear acoustic wave propagation in an elastic solid
with quadratic nonlinearity. Early analytical and experimental studies suggested that the
quasistatic pulse exhibits a right-triangular shape with the peak displacement of the leading
edge being proportional to the length of the tone burst. In contrast, more recent theoretical,
analytical, numerical, and experimental studies suggested that the quasistatic displacement …
