Laterally loaded 3D pile (numgeo vs Abaqus)
In order to show the performance of numgeo in three-dimensional contact analyses, the cyclic loading of a pile in elastic soil using numgeo and Abaqus is investigated.
Only elastic materials are considered in this benchmark. In both programs the penalty method is used to enforce the contact between soil and pile. To be comparable, a fixed factor of \(2\cdot 10^6\) kN/m\(^3\) is used.

Simulation results
The pile head displacement for both programs is depicted in the subsequent figure. A good accordance of the two FE programs is observed.
