Field

Contents

part_ID

Part identifier

(Integer, maximum 10 digits)

part_title

Part title

(Character, maximum 100 characters)

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

Virtual thickness for shells (optional)

(Real)

Define a thickness for shells, only used to calculate gap in interfaces.
Only available for parts containing 3-node and 4-node shells.

hmtoggle_plus1Comments
1.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).
2.Several different parts may have the same material identifier. This is also true for property and subset identifier.
3.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.
4.The virtual thickness for shells is used to compute the gap in interface types 7, 10, 11, 18, 19 and 20; and to compute dsearch in /INTER/TYPE2 in case of Ignore=2 or Ignore=3 and dsearch=0.
5.For shell and thick shell composite parts with /PROP/SH_COMP, /PROP/SH_SANDW, /PROP/TSH_ORTH or /PROP/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.
