1. Reference problem#

1.1. Geometry#

It is a circular plate with radius \(\mathit{OA}\mathrm{=}100\mathit{mm}\), with a crack inclined 30 degrees to the abscissa axis.

1.2. Material properties#

The characteristics of the material are as follows:

\(E\mathrm{=}200000\mathit{MPa}\)

\(\nu \mathrm{=}0.3\)

1.3. Boundary conditions and loads#

The movements are imposed on the outline of the plate. They come from the singular analytical solution in mixed mode (with \({K}_{I}=2.\) and \({K}_{\mathrm{II}}=1.\)).
