 Summary:
 In the present paper, implememtation of Preisach model of hysteresis to elastoplastic analysis of trusses subjected to cyclic is shown. It is also shown that damage effects can be included in presented analysis by introducing basic concepts of continuum damage mechanics. Using finite element method, equilibrium equations are obtained and algorithm for numerical solution is defined. Some advantages of this approach are underlined through several numerical examples.
