The geometry represents only a quarter of the test piece CTJ25:

planes of symmetry: :math:`(x{B}_{0}y)` and :math:`(x{B}_{0}z)`

Thickness: :math:`\mathrm{DD}’=12.5\mathrm{mm}`

Face1: :math:`(A,\mathrm{B0},\mathrm{B1},\mathrm{B2},\mathrm{B3},\mathrm{B4},\mathrm{B5},C,D,E)`

Face2: :math:`(A,\mathrm{B0},\mathrm{B0}\text{'},A\text{'})`

Coordinates of the points (:math:`\mathrm{mm}`):

Material properties
--------------------

The elastic properties of the material are as follows:


* Young's module: :math:`E=2.027027{10}^{11}\mathrm{Pa}`


* Poisson's ratio: :math:`\nu =0.3`
