Frequency Dependent Elastic Property
Description: Defines the frequency or force dependent properties for a PELAS Bulk Data entry.
Format:
Example:
| Field | Definition | Type | Default |
|---|---|---|---|
| PID | Identification number of a PELAS entry. | Integer > 0 | Required |
| TKID | Identification number of a TABLEDi entry that defines the force per unit displacement versus frequency relationship. | Integer > 0 | See Remark 3 |
| TGEID | Identification number of a TABLEDi entry that defines the nondimensional structural damping coefficient versus frequency relationship. | Integer > 0 | See Remark 3 |
| TKNID | Identification number of a TABLEDi entry that defines the nonlinear force per unit displacement versus frequency relationship. | Integer > 0 | See Remark 3 |
Remarks:
- PELAST may only be referenced by CELAS1 or CELAS3 elements.
- For frequency dependent modal frequency response the modes are calculated using nominal Ki values as specified on the PELAS entry.
- The following table summarizes the usage of the PELAST entry in various solution sequences.
