One-way treatment of contact
One-way contact types allow for compression loads to be transferred between the slave nodes and the
master segments. Tangential loads are also transmitted if relative sliding occurs when contact friction is
active. A Coulomb friction formulation is used with an exponential interpolation function to transition from
static to dynamic friction. This transition requires that a decay coefficient be defined and that the static
friction coefficient be larger than the dynamic friction coefficient. The one-way term in oneway contact is
used to indicate that only the user-specified slave nodes are checked for penetration of the master
segments. One-way contacts may be appropriate when the master side is a rigid body, e.g., a punch or die
in a metal stamping simulation. A situation where one-way contact may be appropriate for deformable
bodies is where a relatively fine mesh (slave) encounters a relatively smooth, coarse mesh (master). Other
common applications are beam-to-surface or shell-edge-to-surface scenarios where the beam nodes or
the shell edge nodes, respectively, are given as the slave node set. There are a number of keyword
options that activate one-way contact.
