When told that a system’s response is quite large, a knowledgeable individual will anticipate that nonlinear effects are important. This certainly is the case in acoustics, as exemplified by an explosion, wherein peak pressures might be well above atmospheric.

A theoretical study of “geometric” SP-evanescent (head) waves propagating in an isotropic homogeneous half-space or half-plane with a free boundary shows that these waves can satisfy the condition of absence of effort on the boundary plane if and only if the Lamé parameter λ is vanishingly small, which makes the existence of head waves of this type ...
