This option is used in conjunction with the *SUBSTRUCTURE PROPERTY option to control the type and the source of substructure damping in all analysis procedures using substructures that take damping into account. The rules for using the STRUCTURAL and VISCOUS parameters are the same as the rules for using them for the *DAMPING CONTROLS option within a step definition (see “Defining substructure damping” in “Using substructures,” Section 10.1.1 of the Abaqus Analysis User's Guide, for details).
This option identifies which of the supplied damping options will participate within a substructure. It does not affect the use of the *SUBSTRUCTURE MODAL DAMPING option.
Product: Abaqus/Standard
Type: Model data
Level: Part, Part instance
Set this parameter equal to ELEMENT to request only the condensed structural damping matrix.
Set this parameter equal to FACTOR to request only the structural damping matrix proportional to the condensed substructure stiffness matrix.
Set this parameter equal to COMBINED to request the structural damping matrix that includes the combination of both ELEMENT and FACTOR.
Set this parameter equal to NONE to exclude the structural damping matrix for the elements associated with this substructure property.
If this parameter is omitted or the option is not used as a suboption of the *SUBSTRUCTURE PROPERTY option, the substructure property uses COMBINED as the default with the structural factor specified in the *SUBSTRUCTURE DAMPING option.
Set this parameter equal to ELEMENT to request only the substructure viscous damping matrix defined as a linear combination of the condensed substructure mass and stiffness matrices.
Set this parameter equal to FACTOR to request only the viscous damping matrix.
Set this parameter equal to COMBINED to request a viscous damping matrix that includes a combination of ELEMENT and FACTOR.
Set this parameter equal to NONE to exclude the viscous damping matrix for the elements associated with this substructure property.
If this parameter is omitted or the option is not used as a suboption of the *SUBSTRUCTURE PROPERTY option, the substructure property uses COMBINED as the default with the mass and stiffness proportional Rayleigh damping factors specified under the substructure damping as ALPHA and/or BETA.
