Beam collision with an obstacle is studied in the work. It is presumed that the conditions, under which the motion of the beam before, during and after the collision is planar, are fulfilled. Friction forces between contacting surfaces of both objects are taken into consideration. The problem is solved using the Rigid Finite Element Method. Interaction between the beam and the obstacle, taking into account the elastic properties and surface roughness of the latter one, is modelled using the elastic element. Three different models of the interaction, corresponding to various conditions governing the process, have been presented. Numerical simulations for the three possible variants of collision have been conducted. The results for the three considered cases of the collision have been compared with data obtained using Routh method.
