Abstract: Abstract This paper investigates differences between the grazing-induced bifurcations in impact oscillators with one-sided elastic and rigid constraints by a path-following (continuation) method. The grazing bifurcations are computed and classified for both oscillators. Two-parameter smooth… read more here.

DOI: 10.1016/j.ijnonlinmec.2020.103403
Abstract: Abstract Following the previous work on the degenerate grazing bifurcations of impact oscillators, this paper aims to explore novel two-parameter dynamics near the degenerate grazing points using GPU parallel computing technology. By using the technology,… read more here.

DOI: 10.1016/j.jsv.2018.09.061
Abstract: Abstract The response of vibro-impact oscillators under random excitations has been studied using various techniques in the last three decades. However, the results available were smooth approximations of the intrinsically non-smooth response of vibroimpact oscillators.… read more here.
