Boussinesq problem

This document describes an example that is used to verify the elastic deformation capabilities of PLAXIS. The settlement and stress distribution within a semi-infinite, homogeneous and isotropic soil mass with linear stress-strain relationship, under circular uniform pressure, is studied. PLAXIS results are compared with the analytical solution presented by Boussinesq (1885).
