3D element
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
Prepro: JET3DA.F
Lagamine: JET3DB.F (main subroutine) + JET3DC.F, JET3DN.F

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 |
