Full-field measurements with Digital Image Correlation for vibro-impact characterisation

Broadband shock vibration absorber based on vibro-impacts and acoustic black hole effect

“…As a remark, the interested reader is also referred to the existing literature on vibro-impact NES where the variations of the performances have also been deeply investigated, see e.g. [68,69] for recent experimental reports, and [10,13,[64][65][66][67] for numerical, analytical and experimental studies.…”

Finite contact duration modeling of a Vibro-Impact Nonlinear Energy Sink to protect a civil engineering frame structure against seismic events

“…Recently, Ref. [45] proposed an experimental set-up made of a ceramic particle impacting on two oscillating rigid aluminium plates. A high-speed camera was employed to record the VI NES dynamics, and the particle motion was reconstructed with the aid of digital image correlation.…”

“…Also, Ref. [45] adopted an ad-hoc Hertz-damped model based on an average interpenetration between colliding masses: here, an adjustment was made such that the trajectory of the particle obtained by means of video analysis matched the simulated one under harmonic loading. On the contrary, in the present study the particle is an inelastic sphere interacting with the inner walls according to the elasto-frictional Hertz-Mindlin potential, [48], including more realistic nonlinear viscoelastic dissipative contributions [49][50][51].…”
