CPL2D
Plane or axisymmetric state
Description
Thermomechanical analysis in large deformation with or without metallurgy (in static or dynamic).
The element is defined by 3, 4, 6, or 8 nodes specified in NODES according to the order indicated in the figure.
Type: 202
Implemented by: M. Bourdouxhe, 1985 - Last revised by Charlier & Radu, 1993

| Title (A5) | |
|---|---|
| TITLE | “CPL2D” in the first 5 columns |
| Control data (3I5) | |
| NELEM | Number of elements |
| INDPP | 0 → No specific weight 1 → Specific weight taken into account (or in dynamic analysis) |
| INSIG | = 0 No initial stresses = 1 Initial stresses |
| Only if INDPP = 1 (4G10.0) | |
| WSPE(1) | = specific weight in X direction |
| WSPE(2) | = specific weight in Y direction |
| WSPE(3) | = constant heat source |
| WSPE(4) | = density |
| Initial stresses - Only if INSIG = 1 (3G10.0) | |
| SIGY0 | $\sigma_{y0}$ effective stress $\sigma_y$ at the axis origin |
| DSIGY | Specific weight along Y axis |
| AK0 | $k_0$ ratio $\sigma_x/\sigma_y$ |
| Definition of the elements (5I5/8I5) | |
| NNODE | Number of nodes: 3, 4, 6, 8 - in generalized plane state, one must impose NNODE = 8 and define only the first 8 nodes. The 9th node should not be included |
| NINTE | Number of integration points (1, 3, 4, 7 or 9) |
| LMAT1 | Mechanical material law (in case of metallurgical analysis, number of the ARBTHMET law) |
| LMAT2 | Thermal material law (in general LTHNLS or THMET for metallurgical analysis) |
| LMAT3 | Metallurgical material law (number of the METAMEC law) - put 0 if no metallurgical law |
| NODES(NNODE) | List of nodes |
Results
The results are in order: first the stresses, then the state variables for each integration point.
This gives:
Without metallurgy:
- NINTE (for each point) * sigma (in global axes): $\sigma_x$, $\sigma_y$, $\sigma_{xy}$, $\sigma_z$, $f_x$, $f_y$, $f_{capacitive}$, $f$ due to $\varepsilon^p$
- NINTE * (internal variables): internal variable of the mechanical law
With metallurgy:
- NINTE (for each point) * sigma (in global axes): $\sigma_x$, $\sigma_y$, $\sigma_{xy}$, $\sigma_z$, $f_x$, $f_y$, $f_{capacitive}$, $f_{phase change}$, $0$
- NINTE * (internal variables): internal variable of the mechanical law, percentage of AU, PR, PE, BA, MA, Scheil sum, heat dissipated through phase change, $\lambda$, $\rho c$, indic., $0$
