abstract

An indirect boundary element scheme is employed for the first time to solve two-dimensional, frictional contact problems in the presence of coupling between normal and tangential tractions due to material mismatch and/or geometrical characteristics of the problem under investigation. A fully incremental contact algorithm is used which accounts for changes in the contact regime and the deformed shape of the bodies. The developed algorithm is first validated against the analytical solution obtained for a rigid flat and rounded tilted punch indenting an elastic finite body. The extension of the formulation to treat surface and subsurface cracks, wear and large deformations is also discussed.
