4.1. Characteristics of modeling#
\(\mathrm{2D}\) axisymmetric modeling, AXIS:
Boundary conditions:
\(\mathit{N1}\): \({u}_{y}=0\)
\(\mathit{N2}\): \({u}_{y}=0\)
Charging:
Traction on the face \(\mathrm{[}34\mathrm{]}\) (mesh SEG2)
Assigning the same temperature to all nodes
The total number of increments is \(501\) (\(1\) increment between \(t\mathrm{=}\mathrm{0s}\) and \(t=\mathrm{1s}\), \(500\) increments between \(t\mathrm{=}\mathrm{1s}\) and \(t=\mathrm{2s}\))
Convergence is achieved if residue RESI_GLOB_RELA is less than or equal to \({10}^{\mathrm{-}6}\).
Behavior:
The keywords ELAS and LEMAITRE are used, with the following parameters:
\(E=80000\mathrm{MPa}\)
\(\nu =0.35\)
\(n=4.39\)
\(\frac{1}{K}=0.003944\)
\(\text{UN\_SUR\_M}=0.\)
4.2. Characteristics of the mesh#
Number of knots: 4
Number of meshes: 2
1 QUAD4
1 SEG2
