Wolfgang,
thanks again for your valuable advise. Always a pleasure to receive support
from the boss ;-)

yes the mesh is quite coarse, but I want to investigate the functionality of

there was a small bug in my code I posted above. the following code is
running fine.

Simon,
So far I managed to postprocess derived quantities from the displacement
solution like displacement gradients to get strains and eventually stress
for computation of the mises stress. However, when I view the contour plot
of the von mises stress, the picture looks rather ugly (see
