Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| MID | Material property identification number
that matches the identification number on a MAT2
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 coefficient. (Integer or blank) |
|
| T(GE) | Identification number of a
TABLEMk or TABLEG entry for the damping
coefficient. (Integer ≥ 0 or blank) |
|
| T(ST) | Identification number of a
TABLEMk or TABLEG entry for the tension
stress limit. (Integer ≥ 0 or blank) |
|
| T(SC) | Identification number of a
TABLEMk or TABLEG entry for the compression
limit. (Integer ≥ 0 or blank) |
|
| T(SS) | Identification number of a
TABLEMk or TABLEG entry for the shear
limit. (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 MAT2 entry referenced in field 2.The value in a particular field of the MAT2 entry is replaced (if TABLEM1 or TABLEG is used) or modified (if TABLEM2/3/4 is used) by the table referenced in the corresponding field of this entry. In the example shown, G11 is modified by TABLEMk 32; G33 is modified by TABLEMk 15; and A1 is modified by TABLEMk 62. If Ri is zero or blank, there is no temperature dependence of the field on the MAT2 entry.
- The MATT2 entries may refer to blank entries on the respective MAT2 card. In which case, they will be applied to default values of respective parameters.
- The TEMPERATURE Subcase Information Entry (with type=MATERIAL) is required to activate temperature-dependent material behavior and to define the temperature field (option = SID of TEMP, TEMPD or the SUBCASE ID of a thermal analysis subcase).
- With TABLEM1 or TABLEG, the respective field on MAT2 will be replaced by the table data on MATT2. With TABLEM2/3/4, the respective field of MAT2 will be modified by the table data.
- This card is represented as a material in HyperMesh.
