1.2. Material properties#
Elastic properties:
\(E=165000\mathrm{MPa}\)
\(\nu =0.3\)
Viscous properties:
LEMA_SEUIL law
\(A=14.143{10}^{-13}{\mathrm{MPa}}^{-1}\mathrm{.}{\mathrm{neutron}}^{-1}\)
\(S=0.0788{10}^{10}{\mathrm{MPa}}^{-1}\mathrm{.}{s}^{-1}\)
1.3. Boundary conditions and loads#
Surface strength:
\(F=220\mathrm{MPa}\)
Irradiation:
Irradiation flow: \(1.85{10}^{15}\mathrm{neutrons}\mathrm{.}{\mathrm{cm}}^{2}\mathrm{.}{s}^{-1}\).
Travel required:
Knot \(A\): \(\mathrm{DX}=\mathrm{DY}=\mathrm{DZ}=0\).
Knot \(E\): \(\mathrm{DX}=\mathrm{DY}=0\).
Node \(D\) and node \(H\): \(\mathrm{DX}=0\).
On the first time increment the force goes from \(0\) to its maximum value \(220\mathrm{MPa}\) linearly with respect to time to then be kept constant throughout the duration of the experiment.
