Comments
- Fields 3, 4, and so on, of this entry correspond, field-by-field, to fields 3, 4, and so on, of the MAT1 entry referenced in field 2. The value in a particular field of the MAT1 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, E is modified; TABLEMi 32, A is modified by TABLEMi 15; and ST is modified by TABLEMi 52. Blank or zero entries mean that there is no temperature dependence of the field on the MAT1 entry.
- The MATT1 entries may refer to blank entries on the respective MAT1 card. In this case, they will be applied to default values of respective parameters. Initial values of E, G, or NU will be supplied according to comment 4 on the MAT1 entry.
- Table references must be present for each item that is temperature dependent. For example, it is not sufficient to only give table references for fields 3 and 4 (Young's modulus and shear modulus) if Poisson's ratio is temperature dependent.
- 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 MAT1 will be replaced by the table data on MATT1. With TABLEM2/3/4, the respective field of MAT1 will be modified by the table data.
- This card is represented as a material in HyperMesh.
