Comments
- Fields 3, 4, and so on of this entry correspond, field-by-field, to fields 3, 4, and so on of the MAT8 entry referenced in field 2. The value in a particular field of the MAT8 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, E1 is modified by TABLEMi 32; A1 is modified by TABLEMi 15; and Xt is modified by TABLEMi 52. Blank or zero entries mean that there is no temperature dependence of the fields on the MAT8 entry.
- The MATT8 entries may refer to blank entries on the respective MAT8 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 MAT8 will be replaced by the table data on MATT8. With TABLEM2/3/4, the respective field of MAT8 will be modified by the table data.
