Abstract. The paper puts into evidence the influence of elastic
and viscous nonlinearity upon the dissipated energy in dynamic systems
subjected to harmonic excitation. The physic aspect of the nonlinear behavior
results in a very high energy dissipation as compared with the linear systems
under the same conditions of dynamic load.
RASIPANJE ENERGIJE U SLUČAJU NELINEARNIH
DINAMIČKIH SISTEMA PODVRGNUTIH HARMONOJSKIM POREMEĆAJNIM SILAMA
U radu si prikazani rezultati istraživanja uticaja elastičnih i viskoznih
nelinearnosti na rasipanje nergije dinamičkih sistema podvrgnutih harmonijskim
pobudama. Fizički aspekt u rezultatu nelinearnog ponašanja je veoma veliko
rasipanje energije u poredjenju sa linearnim sistemima pod istim uslovima
dinamičkog opterećivanja.
