The Stress Analysis Of Frictional Punch With
Crack In Plane Elasticity Using Boundary
Element Method

Abstract
In this paper boundary element (BE) formulations for contact and fracture
problems are briefly reviewed and the BE formulation using isoparametric
quadratic elements is applied to the frictional punch with crack, initiating at each
end of the punch. The effects of the present of the crack on the slip-stick
conditions, the stresses within the contact interface and deformations are
examined. In the present BE formulation, the overall system of equation is
obtained by using multi-domain approach in which the contact conditions are
taken into account to couple the different system of equation for each body in
contact. Several types of contact interface conditions are covered including
infinite friction (stick), frictionless and Coulomb friction slip. In order to include
fracture in
