Features of General Contact
• Multiple Contacts Per Node
– The general contact algorithm
does not limit the number of
simultaneous contacts per slave
node.
– Multiple contacts per slave node
may occur when modeling multiple
layers of shells or severe crushing
of a shell.
• Example: Crushing of
aluminum extrusion
