The spotwelds are independent mesh spotwelds. They are modeled with spring type beam (type 13) elements and both sides of the spring are linked to the mesh with tied interfaces (type 2).
The spring property depends on the thicknesses of the parts to link and is defined in the file, <install directory>/environment/.../spotweld/rspdef. This file contains all the parameters to define the spotwelds:
• | minimum length |
• | maximum length |
• | function force vs. thickness |
• | mass and inertia of the spring |
• | rupture parameters |
