The paper presents techniques for the analysis of resonant elastic mechanical structures with nonlinear interactions vibrating with steady or slow-varying amplitudes. A motion law is expressed as a superposition of some set of orthogonal periodic functions by employing the weighted residual techniques. The harmonic balance method is shown to be a special case of the approach.
