adhesives

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.

Nastran

This realization uses the prop_nastran_acm.tcl property script.

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.
