Comments

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. This card is represented as a material in HyperMesh.
