Rod Element Property and Connection
Description: Defines a tension-compression-torsion element without reference to a property entry.
Format:
Example:
| Field | Definition | Type | Default |
|---|---|---|---|
| EID | Element identification number. | Integer > 0 | Required |
| G1, G2 | Grid point identification numbers of connection points. | Integer > 0, G1 ≠ G2 | Required |
| MID | Material identification number. | Integer > 0 | Required |
| A | Area of rod cross-section. | Real | Required |
| J | Torsional constant. | Real or blank | 0.0 |
| C | Coefficient to determine torsional stress. | Real or blank | 0.0 |
| NSM | Nonstructural mass per unit length. | Real or blank | 0.0 |
Remarks:
- Element identification numbers must be unique with respect to all other element identification numbers.
- For structural problems, PROD entries may only reference MAT1 material entries.
- The formula used to compute torsional stress is
where T is the torsional moment.
