Comparison of the calculated y displacement along the force direction for two-dimensional elasticity theory (filled squares) and a finite-element model (open circles) for a point-force displacement. The theoretical displacement goes to negative infinity at large distances. The parameters for the calculations and model are: fixed radius is 5 mm, Young modulus is 2 kPa, Poisson's ratio is 0.3, thickness is 50 μm and force is 200 nN.
