Creates KINCOUP elements for the head and B31 element for the body. The head elements
project and connect to the nodes of the adjoining shell elements that form the hole, and
also to the second row of nodes to form the washer layer. The connector location can be
on the edge of the hole, center of the hole, midpoint in between the two, holes or on
the second row of nodes which form the washer layer.
This connector uses the script prop_abaqus_b31.tcl. Figure 1.
