In several construction components of crane mechanisms, contact loading is very important, which results in the need for the non‐linear analysis. The numerical treatment of contact problems was performed by the finite element method (FEM). The algorithm of the stiffness update with friction, based on the penalty function method, is included in the numerical calculation of the above mentioned contact problems. The potential contact areas are defined throughout the slide‐line contact elements, which enable the handling of the seperation and sliding of the finite amplitude between the deformable bodies.
