Friction is a pervasive nonlinearity in mechanical systems, arising at interfaces from the microscale asperities of surfaces and manifesting in macroscopic performance degradation, wear and control ...

Keywords: seismic isolation; Triple FP isolator modeling; uplift, landing, rocking, bouncing, overturning, flying and contact of bearing components Abstract: Current models that describe the behavior ...

This paper presents the development of a physics-based model of a proportional directional valve with the aim of describing its dynamic behavior while accounting for the influence of friction forces ...

Keywords: Seismic isolation, triple friction pendulum bearing, modeling, heating effects, OpenSees Abstract: This report presents and verifies a revised model of the behavior of triple friction ...

The upper figure shows the viscoelastic toy model proposed here, characterized by only six independent parameters. Surprisingly, this simple mechanical model produces complicated system dynamics, as ...

Friction has been an ever-lasting research problem, ever since the fundamental experimental observations of Leonardo Da Vinci, through the empirical laws postulated by Amontons and Couloumb and until ...
