This work reviews the main techniques to model dynamical systems with contact-impact
events. Regularized and non-smooth formulations are considered, wherein the fundamental …

The selection of the contact force model plays a crucial role in the modeling and analysis of
dynamical systems. The seminal work by Hunt and Crossley, published in 1975, is one of …

Impact behavior is a ubiquitous phenomenon in multibody systems. The contact force model
is a pivotal tool to predict the contact characteristics of multibody systems. At present, there …

Proper modelling of contact/impact phenomenon is critical to ensure reliable description of
the overall dynamic behaviors of mechanical systems. The past few decades witnessed …

In recent years, numerous studies have been conducted regarding the modeling of
contact/impact events between smooth contacting surfaces, ie spheres and cylinders …

A new continuous contact force model for contact problems with complex geometries and
energy dissipations in multibody systems is presented and discussed in this work. The …

The motion of slender rods in narrow tubes involves the coupling of axial movements and
transverse vibrations, in which the transverse vibration exhibits high frequency and chaotic …

Since the Hertzian contact stiffness coefficient is closely related to the power exponent, the
modification of the Hertzian contact stiffness coefficient leads to some problems:(i) the power …
