Problem involving contact between
deformable bodies is of great importance in mechanical and civil engineering as
well as in medicine, food processing, pharmaceuticals and domestic industries.
An implicit solution of large strain, multi-body contact problems is one of the
most demanding problems in computational mechanics. Complex contact
formulations, including various types of smoothing, frictional laws and
sensitivity analysis have become computationally progressively expensive and
for a moderate size problems and can be a bottle neck. Abstract description and
symbolical generation of a numerical code has opened new ways in coding of
contact element routines. In the example the classical master-slave approach is
used and contact smoothing is applied in order to improve accuracy and
numerical efficiency. The augmented Lagrangian
treatment of contact and friction inequality constraints is adopted, which
leads to the full
