Abstract
The essential part of the solution in the context of the finite element method is to locate
possible contact areas reliably and efficiently. Most contact searching algorithms are based on
the definition of a master and a slave contact surface. The searching process consists in
checking contact nodes on the slave boundary against contact segments on the target
boundary. The contact effects are accounted at discrete nodes. The unknown nodal forces are
usually taken as primary unknowns. The main drawback of this undeniably simple and robust
conception is the necessity of paying special attention to situations in which the nodes are
near edges but don't lie within the contact territory of any segment. A new contact searching
scheme is proposed in which the conta
