The Love equation for the normal loading of a rigid cone on an elastic half-space: no need for a modification

A new schematic diagram is presented which shows the displacement paths of surface particles within the contact circle when a rigid cone is loaded normally on an elastic half-space. With the help of this diagram and the information available in the literature, it is argued here that a modification made to the Love equation in 1999 is unnecessary and incorrect. It is also shown that the modification results in an incorrect expression for the surface radial displacement outside the contact circle. Therefore, it is suggested that the modification be dropped forthwith.
