Remarks on Linear Equations

Discussion: “Exact Transient Response of an Elastic Half Space Loaded Over a Rectangular Region of Its Surface” (Norwood, F. R., 1969, ASME J. Appl. Mech., 36, pp. 516–522)

“…However, for z -0, the surface of the half space, the solutions must be reassessed to include the contribution of the Rayleigh surface wave.-.. The additional manipulations necessary to obtain the Milutions for z = {) are shown in [1,5], In addition, as noted by the author, the discusser has found that interior solutions can be u-ed for numerical evaluation of the disturbance near the surface. The discusser's numerical calculations [6, 7] for points near the .--urface show a response similar to that found by Pekeris [4] for surface points.…”

“…4 Chao [3] solved a nonaxisymmetric problem, but he separated the nonaxisymmetric and symmetric parts and used Cagniard's technique only on the latter. 5 Equation and figure numbers refer to equations and figures in the author's paper.…”
