Field	Contents
MID	Material property identification number that matches the identification number on the MAT10 entry. (Integer > 0)
T(BULK)	A TABLEDi entry identification number for the bulk modulus. (Integer > 0 or blank)
T(RHO)	A TABLEDi entry identification number for the mass density. (Integer > 0 or blank)
T(GE)	A TABLEDi entry identification number for fluid material damping coefficient. (Integer > 0 or blank)
T(ALPHA)	A TABLEDi entry identification number for normalized porous material damping coefficient. (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 MAT10 entry referenced in field 2. The value recorded in a particular field of the MAT10 entry is replaced or modified by the table referenced in the corresponding field of this entry. In the example shown, BULK modulus is modified by TABLEDj 10; RHO is modified by TABLEDj 18; G22 is modified by TABLEDi 17; G26 is modified by TABLEDi 12; RHO is modified by TABLEDi 13; GE is modified by TABLEDi 17 and ALPHA is modified by TABLEDi 19.

2.	If the fields are zero or blank, there is no frequency dependence of the field on the MAT10 entry. The MATF10 entries may refer to blank entries on the respective MAT10 card. In which case, they will be applied to default values of respective parameters.

3.	The continuation entries are optional.

4.	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.

5.	This card is represented as a material in HyperMesh.
