Studies by Nishaat (2009) showed that Terzaghi\'s bearing capacity model didn\'t adequately predict the bearing capacity failure in Philippi Dune sands. Nishaat carried out her investigation using a physical model that was built in a geotechnical laboratory. The failure surfaces she observed in the sands did not resemble those predicted by Terzaghi and Meyerhof\'s models.

However the use of a physical model limited her capacity to observe the failure mechanism, the exact extent of plastic deformation and the stress distributions. In this study a simulation of the laboratory experiments done by Nishaat was developed. The simulation had the same failure load, similar patterns of plastic deformation and illustrated a failure mechanism that was different from that predicted by Terzaghi’s model.
