A number of computations have been performed in order to gain an insight into whether or not the non‐linear finite deformation theory must be applied in consolidation problems. These numerical experiments were preluded by tests to determine the correct model size and the fineness of the discretization. For this an analytical solution served as a gauge. The conclusion is that with stiffnesses of the order of ten times the external load, moderate deviations appear in both the effective stresses and the pore pressures.
