Extended Josephson junction driven by dc bias current is studied numerically.Two types of solutions, symmetrical and asymmetrical, are found. Thecurrent-voltage characteristic (IVC) is calculated. The symmetrical solutionsform main histeretic IVC and asymmetrical one create an additional branch.Depending on the bias current value periodic, quasiperiodic and chaotic modesof the junction motion was observed. Dynamics of the junction affected bythermal fluctuations was analyzed. Stability of different states of thejunction is discussed.
