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
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 included 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.
First line:
Surface name. If the surface name is omitted, a default surface that encompasses the entire general contact domain is assumed.
The “words” NO FEATURE EDGES, the “words” PERIMETER EDGES (default), 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.
First line:
Surface name. If the surface name is omitted, a default surface that encompasses the entire general contact domain is assumed. Faces specified on elements other than shell elements, membrane elements, rigid elements, and surface elements will be ignored.
The “word” ORIGINAL (default), the “word” SPOS, the “word” SNEG, or a value between –0.5 and 0.5. The offset defines the distance (as a fraction of the thickness) from the midsurface to the reference surface (containing the nodes of the element). Positive values of the offset are in the positive element normal direction. The default is ORIGINAL, which indicates that the offset specified in element section definitions (via the OFFSET parameter on *SHELL SECTION or *RIGID BODY) will be used.
Repeat this data line as often as necessary. If the offset fraction assignments overlap, the last assignment applies in the overlap region.
First line:
Surface name. If the surface name is omitted, a default surface that encompasses the entire general contact domain is assumed.
The “word” ORIGINAL (default), the “word” THINNING, or a scalar value representing a nominal thickness.
A constant scaling factor (default is 1.0).
Repeat this data line as often as necessary. If the thickness assignments overlap, the last assignment applies in the overlap region.
