BOHLIN’S LIKE INTEGRALS FOR NONCONSERVATIVE MECHANICAL SYSTEMS

Ivana Kovačić

   In this paper the existence of the first integrals for nonconservative mechanical systems is shown. These integrals are obtained by the field method and have a polynomial form similar to the form of Bohlin’s integral for the damped harmonic oscillator, not so well-known as the energy-like integral.
