Forces Acting On A Half-plane
For the special case where, the wedge is converted into a half-plane with a normal force and a tangential force. In that case
Therefore the stresses are
and the displacements are (using Michell's solution)
The dependence of the displacements implies that the displacement grows the further one moves from the point of application of the force (and is unbounded at infinity). This feature of the Flamant solution is confusing and appears unphysical. For a discussion of the issue see http://imechanica.org/node/319.

“Blessed be the inventor of photography! I set him above even the inventor of chloroform! It has given more positive pleasure to poor suffering humanity than anything else that has cast up in my time or is like tothis art by which even the poor can possess themselves of tolerable likenesses of their absent dear ones. And mustnt it be acting favourably on the morality of the country?”
