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 or modified by the table referenced in the corresponding field of this entry. In the example shown, E1 is modified by TABLEDi 32; RHO is modified by TABLEDi 15; and GE is modified by TABLEDi 52.
- Blank or zero entries mean that there is no frequency dependence of the fields on the MAT8 entry. The MATF8 entries may refer to blank entries on the respective MAT8 card. In which case, they will be applied to default values of the respective parameters.
- In Modal Frequency Response Analysis, the frequency-dependency is only used in the frequency response part of the solution, not in the modal analysis part of the solution.
- This card is represented as a material in HyperMesh.
