Towards implicit implementation of penalty based contact boundary condition

This work presents the penalty based implicit coupling between the deformable body and rigid analytical surface. With implicit coupling, it is expected that calculated contact force can be prescribed at contact boundary without under'relaxation which means that optimal convergence rate can be achieved for any user- defined penalty factor. The presented approach can be seen as a first step towards the implementation of the implicit coupling between two deformable bodies in contact. The deformable body is modelled as a linear-elastic with total displacement u as a dependent variable. After discretisation procedure, obtained system of linear algebraic equations is solved in a segregated manner.
