Calculations of the impact of friction and wear on energy consumption, economic
expenditure, and CO 2 emissions are presented on a global scale. This impact study covers …

This review summarizes recent advances in the area of tribology based on the outcome of a
Lorentz Center workshop surveying various physical, chemical and mechanical phenomena …

Crack propagation in rubber-like materials is of great practical importance but still not well
understood. We study the contribution to the crack propagation energy (per unit area) G from …

We study crack propagation in a viscoelastic solid. Using simple arguments, we derive
equations for the velocity dependence of the crack-tip radius, a (v), and for the energy per …

An instrument has been developed that allows in situ optical analysis and tribological
measurements for contacts between solid bodies; an interferometric optical analysis can be …

In this paper we propose a novel methodology to numerically investigate the steady-state
sliding or rolling contact of viscoelastic materials, and in particular to calculate the …

In this work, a numerical method has been developed to investigate the adhesionless
contact mechanics between rough surfaces. To solve the elastic problem a boundary …

We present a novel theory of the adhesive contact of linear viscoelastic materials sliding at
constant velocity against rough substrates. Despite the non-conservative behaviour of the …

We study rubber friction for tire tread compounds on asphalt road surfaces. The road surface
topographies are measured using a stylus instrument and atomic force microscopy, and the …

We present a general energy approach to study the unsteady adhesive contact of
viscoelastic materials. Under the assumption of infinitely short-range adhesive interactions …
