Hi all

I am looking for exact solutions of deflection & stresses for the following problems:

1. Elastic half-space loaded by a circular uniformly distributed load
2. Elastic half-space subjected to a concentrated ring load

I found few journal papers, where reference was given to Timoshenko & Goodier. But I could not trace the explicit equations for exact solutions of deflection & stresses for the above problems.

I would like to know whether any works have been done in EFGM which suggest the best points in the domain where the stresses have to be computed, like in FEM we do have Gauss points which give minimum error for secondary variables. So can any one please suggest some references in this regard?
