Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| part_ID | Part
identifier. (Integer, maximum 10 digits) |
|
| part_title | Part title. (Character, maximum 100 characters) |
|
| unit_ID | Optional unit
identifier. (Integer, maximum 10 digits) |
|
| prop_ID | Property identifier of the
elements in the part. (Integer) |
|
| mat_ID | Material identifier of the
elements in the part mat_ID should be 0 for spring and
rivet elements. (Integer) |
|
| subset_ID | (Optional) Subset identifier to which the part belongs If
omitted, the part belongs to the global model
subset. Default = global model (Integer) |
|
| Thick | (Optional) Virtual thickness for shells. Define a thickness for shells, only used to calculate gap in interfaces. Only available for parts containing 3-node and 4-node shells. (Real) |
Comments
- A part is a homogeneous element assembly. In one part, all elements are of the same type (shells, solids, beams, trusses, springs, rivet, and so on). The elements in a part refer to the same material number (mat_ID), and to the same property identifier (prop_ID).
- Several different parts may have the same material identifier. This is also true for property and subset identifier.
- The value of the virtual shell thickness defined on the Thick field supersedes the thickness defined in the shell property, if the value of the Thick field equals 0 in the /SHELL or /SH3N keyword.
- The virtual thickness for shells is used to compute the gap in interface types 7, 11, 18, 19, 20, 21, 24, and 25; and to compute dsearch in /INTER/TYPE2 in case of Ignore=2 or Ignore=3 and dsearch=0.
- For shell and thick shell composite parts with /PROP/TYPE10 (SH_COMP), /PROP/TYPE11 (SH_SANDW), /PROP/TYPE21 (TSH_ORTH) or /PROP/TYPE22 (TSH_COMP), materials are defined directly in the property card. The failure criteria defined within these materials (for example, LAW25) are accounted for. Material referred to in the /PART card is used only for calculation of time step and contact stiffness.
