Required parameters
- CONSTANTS
-
Set this parameter equal to the number of constants being entered.
Optional parameters
- HYBRID FORMULATION
-
This parameter applies only to
Abaqus/Standard
analyses.
Set HYBRID FORMULATION=INCREMENTAL (default) to use an incremental Lagrange multiplier–based
formulation with hybrid elements.
Set HYBRID FORMULATION=TOTAL to use a total Lagrange multiplier–based formulation with
hybrid elements.
Set HYBRID FORMULATION=INCOMPRESSIBLE to define an incompressible material response with hybrid
elements.
- TYPE
-
Set TYPE=MECHANICAL (default) if the constants are used in defining the mechanical
behavior of the material.
Set TYPE=THERMAL if the constants are used in defining the thermal constitutive
behavior of the material.
If both the user-defined mechanical and the user-defined thermal behavior of
the material are being modeled, the
USER MATERIAL option should be repeated in the material data block such
that each value of the TYPE parameter is used.
- UNSYMM
-
This parameter applies only to
Abaqus/Standard
analyses.
Include this parameter if the material stiffness matrix,
,
is not symmetric or when a thermal constitutive model is used and
is not symmetric. This parameter causes
Abaqus/Standard
to use its unsymmetric equation solution procedures.
Data lines to
define material constants
- First line
-
Give the material constants, eight per line.
Repeat this data line as
often as necessary to define all material
constants.
