Method validation using analysis of numerically deformed beads. 3D contour plots of pressure and principal stresses in the reference simulation (left) and results of the COMPAX method (middle). Reference values based on the volumetric mean of the Cauchy stress tensor (right). (a) The application of periodic surface pressure shows nearly same results for both computations. (b) Larger non-radial displacements lead to local deviations in the contour plot. (c) Stresses reveal inverse local values for the numerical simulation of surface shear, but nearly no difference in mean pressure.
