Bryant", abstract = "Extending the results of our previous study [2], we now investigate the propagation of interior shocks corresponding to the signaling problem of smallamplitude, highfrequency type. We derive a formula for the shock front and show that the previously constructed asymptotic solution is valid on both sides of this front. This solution is further distinguished to a higher order in which the effects of material inhomogeneity are accounted for. Moreover, if = (u, x) represents the eigenvalue under consideration, we show that the singlewavemode boundary disturbance of [2] can lead only to a shock. We also derive an entropy condition for the shock wave. As an application of our theory, the fluidfilled hyperelastic tube problem of [7] is further examined and an example calculation made in which we show that a compressive shock wave is generated at the shockinitiation point. This demonstration is effected as a particular example of the solution to a general bifurcation problem.", }
