In this dissertation, a freight train suspension system is presented for all possible types of motion. The suspension system experiences impacts and friction between wedges and bolster. The impacts cause the chatter motions between wedges and bolster, and the friction will cause…

This thesis presents observations from the Bosphorus (Strait of Istanbul), Turkey, made to study the effects of mixing, entrainment and frictionally induced shear on the dynamics of an exchange flow. The well known two-layer structure with an upper layer of brackish Black Sea wa…
In real life, immediately after joint replacement, the artificial joint is actually bathed in blood (and clotted blood) instead of synovial fluid. Blood contains large molecules and cells of size ~ 5 to 20 μm suspended in plasma and considered to be a non-Newtonian (pseudoplasti…
Static friction, a force fundamental to nearly every mechanical system from micro-machines to basketball shoes to tectonic plates, is in fact anything but static. In contrast to the simplified version taught in high-school, static friction is actually extremely dynamic, complex,…
Two approaches for computational contact mechanics are explored to provide an accurate and robust numerical simulation of frictional contact. First, a novel quasi-static contact algorithm (Method of First Violation) is developed, which provides a solution over the load history t…
This thesis presents results of centrifuge model tests and three-dimensional large deformation finite element (LDFE) analysis on axial pipe-soil sliding behaviour of partially embedded subsea pipelines. 3D re-meshing and interpolation technique with small strain (RITSS) approach…
Within pressurised Metered Dose Inhalers (pMDIs) the contact between the valve components and elastomeric seals is of major significance, representing the main contributory factor to the overall system frictional characteristics. Therefore, the seal performance is extremely impo…
The fundamental theories of heat generation and transfer at the friction interface of a brake assume either matching or not matching surface temperatures by having a varying or uniform heat partition ratio respectively. In the research presented the behaviour of heat partition h…
