Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| MID | Material property
identification number that matches the identification number on
MAT3 entry. (Integer > 0) |
|
| T(EX), T(ETH), T(EZ) | Identification number of a
TABLEMi or TABLEG entry
for the Young's moduli in the x,
and z directions. Default = blank (Integer ≥ 0 or blank) |
|
| T(NUXTH), T(NUTHZ), T(NUZX) | Identification number of a
TABLEMi or TABLEG entry

,
z and zx directions. Default = blank (Integer ≥ 0 or blank) |
|
| T(RHO) | Identification number of a
TABLEMi or TABLEG entry
for the mass density. Default = blank (Integer ≥ 0 or blank) |
|
| T(XTH), T(GZX), T(THZ) | Identification number of a
TABLEMi or TABLEG entry

,
z and zx directions. Default = blank (Integer ≥ 0 or blank) |

| T(AX), T(ATH), T(AZ) | Identification number of a
TABLEMi or TABLEG entry
for the thermal expansion coefficients in the x,
and z directions. Default = blank (Integer 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 MAT3 entry referenced in field 2. The value in a particular field of the MAT3 entry is replaced or modified by the table referenced in the corresponding field of this entry. In the example shown, EX is modified; TABLEMi 32, EZ is modified by TABLEMi 19; and GZX is modified by TABLEMi 52. Blank or zero entries mean that there is no temperature dependence of the field on the MAT3 entry.
- Any quantity modified by this entry must have a value on the MAT3 entry.
- 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.
- For temperature-dependent material table lookup for an element with different temperatures at each node, the average temperature of all nodes of the element is considered as reference temperature for table lookup for that particular element.
