Cette thèse traite du problème de l'écoulement d'un fluide dans des interfaces étroites entre des solides en contact sous un chargement normal, ce qui est important pour de nombreuses applications en tribologie, ingénierie et géophysique. Le tr

We developed a computational framework for simulating thin fluid flow in narrow interfaces between contacting solids, which is relevant for a range of engineering, biological and geophysical applications. The treatment of this problem requires coupli

A pressure driven flow in contact interface between elastic solids with wavy surfaces is studied. We consider a strong coupling between the solid and the fluid problems, which is relevant when the fluid pressure is comparable with the contact pressur

We study the mechanical contact between a deformable body with a wavy surface and a rigid flat taking into account pressurized fluid trapped in the interface. A finite element model is formulated for a general problem of trapped fluid for frictionles

This corrigendum aims to correct errors in the graphs axes ranges resulting from miss-scaling of the results in Kaczmarczyk et al. 2017 in CMAME.

The standard approach to mechanical problems requires the solution to the mathematical equations that describe both the conservation laws and the constitutive relationships, where the latter is obtained after fitting experimental data to a certain ma

Triboelectric nanogenerators (TENG) transform mechanical energy into electrical energy as a result of contact between suitably chosen surfaces. Surface roughness plays a key role in the performance of contactseparation TENG, defining the ratio of rea
