TIE
Optional parameters:
ADJUST
Set ADJUST=YES (default) to move all tied nodes on the slave surface onto the m aster surface in
the initial configuration, without any strain.
Set ADJUST=NO if the slave nodes will not be moved. This is the default if the slave surface
belongs to a substructure or if one or more of the surfaces is beam element-based.
CONSTRAINT RATIO
This param eter applies only when two surfaces wit
h rotational degrees of freedom are tied with an
offset but the NO ROTATION parameter is used.
Set this param eter equal to the fractional distan
ce between the master reference surface and
the slave node at which the translational constraint should ac t. By d
efault, ABAQUS will attempt
to choose this distance such that the translational constraint acts pre
cisely at the interface.
CYCLIC SYMMETRY
This parameter applies only to ABAQUS/Standard analyses.
Include this parameter to invoke a constraint between the faces bounding a repetitive sector of
a cyclic symmetric structure. This parameter can be used o nly in conjunction with the
*
CYCLIC
SYMMETRY MOD EL option.
NO ROTATION
Include this parameter if rotation degrees of freedom should not be tied. If this parameter is om itted,
any existing rotation degrees of freedom will be tied if applicable, in addition to the translation
degrees of freedom .
NO THICKNESS
Include this parameter to ignore shell thickne ss effects in calculations involving position tolerances
and adjustments for initial gaps.
TYPE
Set TYPE=SURFACE TO SUR FACE (default for most cases in ABAQ US/Standard) to have the tie
coefficients generated such that stress accuracy is optimized for the specified surface type pairings.
Set TYPE=NODE TO SURFACE (default for all cases in ABAQUS/Explicit) to have the tie
coefficients generated according to the interpolation functions at the point where the slave node
projects onto the m aster surface.
Data lines to define the surfaces forming the constraint pairs:
First line:
1. The slave surface name.
2. The master surface name.
Repeat this data line as often as necessary to define all the surfaces for ming the constraint pairs. Each
data line defines a pair of surfaces that will be tied tog ether.
