Abstract
In this work, the Caputo fractional derivative is used to construct the Lagrangian and the Hamiltonian formulations for nonconservative mechanical systems. The Euler-Lagrange equations are derived using a variational principle. Hamilton’s equations of motion are then obtained by introducing a set of momenta and a Hamiltonian in a manner that is more consistent with that used in conventional classical mechanics. The proposed formalism is applied to the damped harmonic oscillator, as an example.
