Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| MID | Material property identification number that
matches the identification number on the
MAT3 entry. (Integer > 0) |
|
| T(EX), T(ETH), T(EZ) | TABLEDi entry identification numbers for Young's moduli in the
x,
and z directions. Default = blank (Integer ≥ 0 or blank) |
|
| T(NUXTH), T(NUTHZ), T(NUZX) | TABLEDi entry identification numbers for Poisson's ratios in
the x
,
z and zx directions. Default = blank (Integer ≥ 0 or blank) |
|
| T(RHO) | A
TABLEDi entry identification number for the mass
density. Default = blank (Integer ≥ 0 or blank) |
|
| T(GZX) | A
TABLEDi entry identification number for the shear
modulus. Default = blank (Integer ≥ 0 or blank) |
|
| T(AX), T(ATH), T(AZ) | TABLEDi entry identification numbers for thermal expansion
coefficients in the x,
and z directions. Default = blank (Integer or blank) |
|
| T(GE) | A
TABLEDi entry identification number for the damping
coefficient. Default = blank (Integer > 0 or blank) |
Comments
- Fields 3, 4, and so on of this entry correspond, field-by-field, to fields 3, 4, and so on of the MAT3 entry referenced in field 2. The value in a particular field of the MAT3 entry is replaced or modified by the table referenced in the corresponding field of this entry. In the example, EX is modified; TABLEDi 32, RHO is modified by TABLEDi 19; and GE is modified by TABLEDi 52.
- Blank or zero entries mean that there is no frequency dependence of the field on the MAT3 entry. Any quantity modified by this entry must have a value on the MAT3 entry.
- 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.
