DOI: 10.1007/s11012-017-0641-1
Abstract: Models with impact or dry friction, yielding discontinuous velocities or accelerations, have motivated research for appropriate numerical methods in the community of non-smooth dynamics. In this work, we apply such methods on the grand piano… read more here.

DOI: 10.1007/s11012-017-0648-7
Abstract: Abstract We consider a dry friction oscillator on a moving belt with both the Coulomb friction and a small nonlinear addition which can model e.g. the Stribeck effect. By using the perturbation theory, we establish… read more here.

DOI: 10.1007/s11044-018-09637-1
Abstract: We consider the dynamics of an absolutely rigid body moving along a rough horizontal plane. We assume that the plane deforms during the motion so that the contact patch is non-planar and has non-zero, but… read more here.

DOI: 10.1007/s11071-016-3117-2
Abstract: Bolted joints are prevalent in most assembled structures; however, predictive models for their behavior do not exist. Calibrated models, such as the Iwan model, are able to predict the response of a jointed structure over… read more here.
