Figure 27:

x-displacement of the center point in Figure (24) for the steady state elastic band benchmark (Section 4.5) for different choices of elements and numerical Poisson ratio. The solid DOF range from m = 42 to m = 3255. Note that for ν_stab = .49995 low order elements produce volumetric locking, and higher order elements are needed for convergence at reasonable numbers of DOF. Also note that the differences between different methods are somewhat less pronounced in these tests.
