Field |
Contents |
|---|---|
MID |
Material property identification number that matches the identification number on MAT1 entry. (Integer > 0) |
T(E1) |
Identification number of a TABLEMi entry for the Young’s modulus 1. (Integer > 0 or blank) |
T(E2) |
Identification number of a TABLEMi entry for the Young’s modulus 2. (Integer > 0 or blank) |
T(NU12) |
Identification number of a TABLEMi entry for the Poisson’s ratio 12. (Integer > 0 or blank) |
T(G12) |
Identification number of a TABLEMi entry for shear modulus 12. (Integer > 0 or blank) |
T(G1Z) |
Identification number of a TABLEMi entry for transverse shear modulus 1Z. (Integer > 0 or blank) |
T(G2Z) |
Identification number of a TABLEMi entry for transverse shear modulus 2Z. (Integer > 0 or blank) |
T(RHO) |
Identification number of a TABLEMi entry for mass density. (Integer > 0 or blank) |
T(A1) |
Identification number of a TABLEMi entry for the thermal expansion coefficient 1. See comment 3. (Integer or blank) |
T(A2) |
Identification number of a TABLEMi entry for the thermal expansion coefficient 2. (Integer or blank) |
T(Xt) |
Identification number of a TABLEMi entry for the tension stress/strain limit 1. (Integer > 0 or blank) |
T(Xc) |
Identification number of a TABLEMi entry for compression stress/strain limit 1. (Integer > 0 or blank) |
T(Yt) |
Identification number of a TABLEMi entry for tension stress/strain limit 2. (Integer > 0 or blank) |
T(Yc) |
Identification number of a TABLEMi entry for compression stress/strain limit 2. (Integer > 0 or blank) |
T(S) |
Identification number of a TABLEMi entry for shear stress/strain limit. (Integer > 0 or blank) |
T(GE) |
Identification number of a TABLEMi entry for structural damping coefficient. (Integer > 0 or blank) |
T(F12) |
Identification number of a TABLEMi entry for Tsai-Wu interaction term. (Integer > 0 or blank) |
| 1. | 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 or modified 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. |
| 2. | 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. |
| 3. | 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). |
| 4. | With TABLEM1, 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. |
| 5. | This card is represented as a material in HyperMesh. |
