2) Flat plate with circular hole under uniform tension
This case of a flat plate with circular hole under uniform tension (cf. Fig.1) can be calculated analytically,
but the behaviour of the solution is highly non-linear, cf. Eqn.1, especially in the area
of the inner hole-boundary. To obtain the solution transformation in cylindrical coordinates is neccassary,[1,2].
Linearly elastic, isotropic material is assumed leading to an augmentation of stress by three at the hole flank.
To save computer resources, symmetry boundary conditions were used.

As another feature of the programm non-matching block-interfaces can also be handled by the routines for structure mechanics,
cf. Fig.2, which was tested during this computation.
