Auxiliary Output Points Along Bar Element Axis
Description: A series of points along a bar element x-axis may be defined with this entry for stress and force recovery output.
Format:
Example:
Alternate Format and Example:
| Field | Definition | Type | Default |
|---|---|---|---|
| EID | CBAR element identification number. | Integer > 0 | Required |
| SCALE | Defines scale of Xi values. Must be one of following character variables: LE or FR. | Character | Required |
| Xi | Series of locations along element x-axis for stress and force data recovery. | Real > 0.0 | 0.0 |
| DELTAX | Incremental distance along element x-axis. | Real | 0.0 |
| NPTS | Number of stress recovery points, not including the endpoints. | Integer > 0 | 0 |
Remarks:
- This entry defines intermediate locations on the axis of selected CBAR elements for additional data recovery. The values of Xi are actual distance along the length if SCALE = LE. If SCALE = FR, the values of Xi are ratios of actual distance to the bar length.
- When the alternate format is used, a series of locations Xi = X[i-1] + DELTAX, i = 1, 2, 3…, NPTS are generated.
- If a CBARAO entry is specified for a bar element and stress and/or force output is requested, then the stresses and/or forces will be calculated at each location Xi and output as a separate line. The force and stress values at the endpoints of the beam will always be output.
- Intermediate loads on the element defined by the PLOAD1 entry will be accounted for in the calculation of element stresses and forces. If no PLOAD1 entry is defined for the element, the shear forces are constant, the moments are linear, and the definition of additional points is not necessary.
- For each bar element, either the basic format or the alternate format, but not both, may be used. A maximum of six internal points can be specified with the basic form and nine with the alternate form. The endpoints should not be listed because data will be generated for them, as explained in Remark 3. If more than six unequally spaced internal points are desired, it is advisable to subdivide the bar into two or more elements.
