*SURFACE PROPERTY ASSIGNMENT
18.51 *SURFACE PROPERTY ASSIGNMENT: Assign surface properties to a surface for the
general contact algorithm.
This option is used to modify surface properties for surfaces that are involved in general contact interactions
in ABAQUS/Explicit. It must be used in conjunction with the *CONTACT option.
Product: ABAQUS/Explicit
Type: Model or history data
Level: Model, Step

Required parameter:
PROPERTY
Use this parameter to specify the property type being assigned. To modify more than one type of
surface property, use this option more than once with different values for the PROPERTY parameter.
Set PROPERTY=FEATURE EDGE CRITERIA to control which feature edges should be
activated in the general contact domain.
Set PROPERTY=OFFSET FRACTION to assign the surface offset as a fraction of the surface
thickness.
Set PROPERTY=THICKNESS to assign the surface thickness.
Data lines for PROPERTY=FEATURE EDGE CRITERIA:
First line:
1. Surface name. A non-blank surface name is required if the ALL EDGES or PICKED EDGES
options are specified. If the surface name is omitted when using the PERIMETER EDGES,
NO FEATURE EDGES, or cutoff feature angle options, a default surface that encompasses the
entire general contact domain is assumed.
2. The “words” PERIMETER EDGES (default), the “words” ALL EDGES, the “words” PICKED
EDGES, the “words” NO FEATURE EDGES, or a scalar value representing the cutoff feature
angle (in degrees).
Repeat this data line as often as necessary. If the feature edge criteria assignments overlap, the last
assignment applies in the overlap region.
