This paper presents a simple, practical method of modelling non‐destructive impacts
macroscopically, where the impact force and post‐impact motion of the impacting bodies are …

This paper presents experimental and numerical investigations of resonance vibrations of
an impact damper other than at its original resonance frequency. In the numerical modelling …

Non-smooth stiffness and damping characteristics are commonly encountered in
mechanical systems. The specific physical contacts considered in this paper are impact and …

Compliant impact models are the only analytical means one has to predict the forces
generated in an impact. It was not until 1975, with Hunt and Crossley, that a complete …

Seismic pounding affects some buildings and bridge spans with insufficient expansion
joints. During pounding, structures exert repeated hammer-like blows on adjacent structures …

Impact is a phenomenon that is ubiquitous in mechanical design; however, the modeling of
impacts in complex systems is often a simplified, imprecise process. In many high fidelity …

In this paper the steady state behaviour of a beam system with a periodically moving support
and an elastic stop is analysed both numerically and experimentally. In the numerical …

[en] This contribution refers to the behaviour of reinforced concrete structures impacted by
deformable missiles. The difference with hard missile impact problems, about which …

Reducing the severity of an impact to a structure or a multibody system is a significant aspect
of engineering design. This requires the knowledge of variations of the resulting contact …
