Set this parameter equal to the name of the amplitude curve that defines a
time-dependent scale factor for contact stabilization over the step. If this
parameter is omitted, the scale factor ramps linearly from unity to zero over
the step.
RANGE
Set this parameter equal to the clearance at which the stabilization becomes
zero; no contact stabilization is applied where the separation between surfaces
exceeds this value. By default, this clearance is calculated by
Abaqus/Standard
based on the facet sizes on contact surfaces.
REDUCTION PER INCREMENT
Set this parameter equal to a factor by which
Abaqus/Standard
will reduce the contact stabilization coefficient per increment. The default
value is 0.1 for the interactions specified on the data lines of this option.
RESET
Include this parameter to cancel carryover effects from contact
stabilization specifications involving nondefault amplitudes that appeared in
previous steps. This parameter cannot be used in conjunction with any other
parameters. There are no data lines if this parameter is included.
SCALE FACTOR
Set this parameter equal to a factor by which
Abaqus/Standard
will scale the contact stabilization coefficient. The default value is unity
for the interactions specified on the data lines of this option.
Set SCALE FACTOR=USER ADAPTIVE to scale the contact stabilization coefficient by a factor
that decreases over iterations within each increment, according to the pattern
specified on the data line.
TANGENT FRACTION
Set this parameter equal to a factor that scales the contact stabilization
coefficient in the tangential direction only. The default value is zero, such
that no contact stabilization is applied in the tangential direction.
Data
lines if the RESET parameter is omitted
First line
The name of the first surface. If the first surface name is omitted, a
default surface that encompasses the entire general contact domain (including
all nodes and facets) is assumed.
The name of the second surface. If the second surface name is omitted or is
the same as the first surface name, the specified stabilization settings are
assigned to contact interactions between the first surface and itself.
Repeat this data line as
often as necessary. Specifying named
XFEM-based crack surfaces on the data lines is
not currently
supported.
