abstract = {In this paper we compare two models to compute the
isostatic response of the Earths lithosphere to an external
load. The lithosphere is modeled as a linear elastic solid.
The two models differ in the mathematical formulation of
the problem, their applicability in the incompressible
limit, the choice of the finite elements used for
discretization, and the solution strategy for the arising
algebraic problem. The efficiency and accuracy of both
models are compared via extensive numerical experiments in
2D and 3D.}
