%0 Journal Article %T Analytical prediction of stick-slip chaos in a double self-excited Duffing-type oscillator %A Jan Awrejcewicz %A Mariusz Holicke %J Mathematical Problems in Engineering %D 2006 %I Hindawi Publishing Corporation %R 10.1155/mpe/2006/70245 %X We have analytically predicted homoclinic bifurcations in a class of double self-excited Duffing-type oscillators using the Melnikov-Gruendler approach. Both stick-slip and smooth chaotic behaviors predicted analytically have been confirmed by numerical simulations. %U http://www.hindawi.com/journals/mpe/2006/070245/abs/
