Rod Element Property
Description: Defines the properties of rod elements (CROD entry).
Format:
Example:
| Field | Definition | Type | Default |
|---|---|---|---|
| PID | Property identification number. | Integer > 0 | 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:
- PROD entries must all have unique property 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.
