Nonlinear evolution of initially sine-like wedge acoustic waves
conference contribution
posted on 2010-05-06, 15:40 authored by Victor V. Krylov, A.P. Mayer, D.F. ParkerIn this paper the nonlinear behaviour of antisymmetric
wedge acoustic waves propagating along the tip of a sharp
elastic wedge is investigated theoretically. The nonlinear
evolution equation is derived taking into account
geometrical-acoustics approximation for wedge waves. In
contrast to the case of surface acoustic waves for which
the quadratic nonlinearity dominates, the lowest order of
nonlinearity in this equation is cubic. For arbitrary
propagation distances, the numerical solution taking into
account 1O interacting wave harmonics has been carried
out. The results show that an initially sine-like
antisymmetric wedge wave distorts to a wave of
trapezoidal form propagating with changed phase velocity.
