Restriction: Available in Abaqus, Nastran, and OptiStruct.
Abaqus
Creates a row of hexa/penta elements for the body and numerous DCOUP3D/KINCOUP
elements for the head. The head elements project and connect to the nodes of the
adjoining shell elements. If there is a direct normal projection then a KINCOUP
element will be used, if there are only non-normal projections then DCOUP3D elements
will be created. The size (thickness) for the hexa and/or penta elements depends on
the chosen option: shell gap, (T1+T2)/2, mid thickness, const. thickness, maintain
gap.
Note: The exact hexa position is also influenced by the option consider
shell thickness and offset for hexa positioning. See hexa positioning for hexa
adhesives and ACMs for details.
This realization uses the prop_abaqus_acm.tcl property
script. Figure 1.
Nastran
This realization uses the prop_nastran_acm.tcl property
script. Figure 2.
OptiStruct
Creates a row of hexa/penta elements for the body and numerous RBE2/RBE3 elements for
the head. The head elements project and connect to the nodes of the adjoining shell
elements. If there is significant curvature in the area connector then penta
elements will be created, otherwise hexa elements will normally be created. If there
is a direct normal project then an RBE2 elements will be used, if there are only
non-normal projections then RBE3 elements will be created.
This realization also uses the prop_nastran_acm.tcl property
script. Figure 3.
