JET3D
3D element
Description
Element adapted to the simulation of rolling.
For cases of complete or normal orthotropicity of the rolled sheet, the numbering of nodes must be done to have the local Z axis perpendicular to the rolled sheet.
Type: 25
Implemented by: L. Kaiping, 1990

| TITLE | “JET3D” in the first 5 columns |
| Control data (4I5, 3G10.0, I5, G10.0, I5) | |
| NELEM | Number of elements |
| INDPP | 0 → No specific weight (or specific mass if NTANA = -1) 1 → Specific weight taken into account (or specific mass if NTANA = -1) |
| METHD | Method for the stress matrix 0 → New approach (default value) 1 → Classic approach |
| ISHEAR | Index to avoid shear locking 0 → Value computed by the program (Default value) 1 → Value fixed to 1.0 (full integration) 2 → Value fixed to 0 (reduced integration) 3 → Value given by the user |
| $\beta_{12}$ | Coefficients for the control of shear locking = 0 if ISHEAR ≠ 3 |
| $\beta_{13}$ | |
| $\beta_{23}$ | |
| IANGL | 0 → Use global axes 1 → Use local axes defined by the angle $\alpha$ - Complete orthotropic case 2 → Use local axes that coincide with intrinsic axes - Normal orthotropic case |
| ANGLE | = angle between global X axis and rolling direction if IANGL = 1 = 0 else |
| MLAW | Index for the material constitutive law 0 → Global approach (Default value) 1 → Local approach (can call any law except laws specific to JET3D element) |
| Only if INDPP = 1 (4G10.0) | |
| WSPE(1) | = specific weight in X direction |
| WSPE(2) | = specific weight in Y direction |
| WSPE(3) | = specific weight in Z direction |
| WSPE(4) | = density |
| Definition of the elements (I5/8I5) | |
| LMATE | Material law |
