14.Material coordinates are fixed at the equilibrium positions of points in the string and so act as labels of these points. Thus, if the point P of the string has the material coordinates [X,0,0], then its longitudinal position at time t is given by the dynamic spatial coordinate , where ξ is the longitudinal displacement of P from its equilibrium position. Elementary treatments of linear transverse waves do not distinguish between the longitudinal material and spatial coordinates because is considered to be negligible. This approximation cannot be made in the derivation of the Kirchhoff-Carrier wave equation, however, and so the fact that the wave equation is a function of the material coordinate X and not the spatial coordinate x is being explicitly made in this Comment.

27.The reason for the approximately equal sign in e0 is that for the numerical simulations, Lr/L0 rather than e0 was the defined parameter, with e0= (Lr/L0)−1−1. The reason for using Lr/L0 to be the stretching parameter was to be consistent with the numerical modeling of a string as a chain of point masses developed in Ref. 29.

Abstract

In a recent paper, Whitfield and Flesh found unusual bowing behavior in the waveform of a guitar string for large amplitude plucks. This Comment discusses the theory needed to understand this nonlinear effect, and it is shown that this theory provides reasonably good qualitative agreement with the observed wave form. This theory is interesting because: (i) it allows one to quantify the boundary between linear and nonlinear behavior in terms of key physical parameters; (ii) it reveals the importance of taking into account longitudinal displacements even when they are much smaller than the associated transverse displacements; and (iii) it reveals that dispersion due to tension changes and dispersion due to flexural rigidity have very similar functional forms, which leads to the question of when one effect can be neglected in comparison to the other.
