Initial Receding Contact Problem Involving
Large Displacements

Abstract
An algorithm based on the Boundary Element Method is utilised for the frictionless and fric-
tional loading process in the specific case of receding contact problem. The formulation is
limited to elastic behaviour of the materials involved and a Coulomb Type of friction is as-
sumed. The contact constraints are applied node on element using quadratic shape functions to
distribute the geometry, tractions and displacements at the contact zone. Therefore, the usual
way of imposing the contact conditions (node-pair) is abandoned. That allows us to deal with
the large displacement problem using an incremental procedure (Updated Lagrangian Ap-
proach). At least one increment of load must be done for each node changing its contact con-
dition and additi
