A nonlinear dynamic system with a finite number of degrees of freedom, which describes the forced oscillations of a beam with two breathing cracks, is obtained. The cracks are located on opposite sides of the beam. The Bubnov-Galerkin method is used to derive the nonlinear dynamic system. Infinite s...
