The model of a non-smooth oscillator, which exhibits two discontinuity boundaries in the phase space, is considered in order to investigate the dynamics of vibrating systems characterized by the occurrence of multiple frictional contacts. The physical system consists of a visco-elastic oscillator which is continuously in contact with two different rough(More)
This study investigates the scattering of guided waves from a discontinuity exploiting the principle of reciprocity in elastodynamics, written in a form that applies to waveguides. The coefficients of reflection and transmission for an arbitrary mode can be derived as long as the principle of reciprocity is satisfied at the discontinuity. Two elastodynamic(More)
