+## Equations
+
+We solve a linear elastic small deformation problem on a quarter of a plate with hole put under tension on the top boundary.
+
+See the TODO: {asset:797:link}-PDF for detailed problem description.

+
+## Results and evaluation
+
+Result showing the displacement field and ten-fold overscaled distortion:
