Surface smoothing technique for surface-to-surface contact.

Problem description

Examples are given to verify the behavior of the surface smoothing technique, which helps to improve contact stress accuracy. The method applies to both finite-sliding and small-sliding surface-to-surface contact.

Results and discussion

These results show significant accuracy improvement for models subject to relatively small deformation compared to equivalent analyses without the surface smoothing technique.
