A non‐linear three‐dimensional finite element procedur is developed and applied for the analysis of pile group foundations. The numerical procedure allows for elastic, non‐linear elastic and elastic‐plastic hardening behaviour of sand. In order to include the interaction effects involving relative slip and debonding, the thin‐layer interface element is used. The predictions for displacements and loads obtained from the numerical procedure are compared with laboratory model test results of a pile group. Displacements, stresses and forces distribution in various components of the pile group are also examined. Furthermore, the effects of the non‐linear soil response and relative motions at the interface are indentified and discussed.
