Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| MID | Material property identification number that
matches the identification number on a
MAT9 entry. (Integer > 0) |
|
| T(Gij) | Identification number of a TABLEMk or TABLEG
entry for the terms in the material property matrix. (Integer ≥ 0 or blank) |
|
| T(RHO) | Identification number of a TABLEMk or TABLEG
entry for the mass density. (Integer ≥ 0 or blank) |
|
| T(Ai) | Identification number of a TABLEMk or TABLEG
entry for the thermal expansion coefficients. (Integer ≥ 0 or blank) |
|
| T(GE) | Identification number of a TABLEMk or TABLEG
entry for the damping coefficient. (Integer ≥ 0 or blank) |
Comments
- Fields 3, 4, and so on of this entry correspond, field-by-field, to fields 3, 4, and so on of the MAT9 entry referenced in field 2. The value recorded in a particular field of the MAT9 entry is replaced (if TABLEM1 or TABLEG is used) or modified (TABLEM2/3/4 is used) by the table referenced in the corresponding field of this entry. In the example shown, G11 is modified by TABLEMj 32; G14 is modified by TABLEMj 18, and so on. If the fields are zero or blank, there is no temperature dependence of the field on the MAT9 entry.
- The MATT9 entries may refer to blank entries on the respective MAT9 card. In which case, they will be applied to default values of respective parameters.
- The continuation entries are optional.
- Temperature-dependent materials can be activated at the subcase level via different options (such as TEMP(MAT), TEMP(BOTH), DLOAD (via TLOAD1, TLOAD2 and TEMP/TEMPD Bulk Data Entries), etc.) depending on the subcase type.
- With TABLEM1 or TABLEG, the respective field on MAT9 will be replaced by the table data on MATT9. With TABLEM2/3/4, the respective field of MAT9 will be modified by the table data.
- This card is represented as a material in HyperMesh.
