Sažetak

In this work, fractional integral calculus is applied in order to derive Lagrangian mechanics of nonconservative systems. In the proposed method, fractional time integral introduces only one parameter, a, while in other models an arbitrary number of fractional parameters (orders of derivatives) appears. Some results on Hamiltonian part of mechanics, namely Hamilton equations, are obtained and discussed in detail.
