Abstract
In this paper high-order triangular elements are implemented in the framework of
the Arbitrary Lagrangian-Eulerian method for the analysis of large strain consolidation
problems in geomechanics. The theory of consolidation, as well as details of the high-order
elements, including cubic (10-noded), quartic (15-noded), quantic (21-noded) and sextic (28-
noded) elements are discussed. The accuracy and the efficiency of high-order elements in the
analysis of consolidation problems are demonstrated conducting a small deformation analysis of
the soil under a strip footing as well as a large deformation analysis of a vertical cut subjected to a
surcharge loading. Based on the numerical results, it is shown that high-order elements not only
improve the accuracy of solution but can also significantly decrease the required
computational time. It is also demonstrated that assuming identical order for displacement
shape functions and the pore water pressure shape functions does not affect the stability of the
time-marching analysis of consolidation nor the accuracy of the numerical predictions.
