The increasing interests in micro-electro-mechanical systems (MEMS) has raised the requirement for photoresist materials with improved friction and wear properties for mechanically loaded 3D shaped microstructures. In this work, SU8 photoresist layers rein ...
The dry wear and tribocorrosion behaviour of pulsed plasma treated and non-treated Ni-Cr alloys sliding against alumina at 15 N were investigated by using a reciprocating wear test rig equipped with an electrochemical cell. The pulsed plasma treatment prod ...
The problem of mechanical contact is a truly multiscale one. Atomistic effects that violate continuum theory dominate the deformations of contacting asperities, while the interactions between distant asperities occur through long-range elasticity. This the ...
Valuable insights into the wear-corrosion behavior of metals, as well as into the tribocorrosion field through the development of simulation models of tribocorrosion experiments, can contribute in rationalizing wear-accelerated experiments and their open c ...
For a large number of non-oxideceramic/metal as well as for non-oxide particulate reinforced composite/metal tribocouples,oxidative wear is reported to play a major role in the overall damage and material removal process.The designing of new materials with ...
In this thesis, an original law of adhesion is developed and then coupled to the classical law of unilateral contact with threshold friction, in order to study the phenomenon of fibre/matrix debonding in composite materials. This tribological law is develo ...
The bridging of different research disciplines such as computer modelling and design practice requires full understanding of both. Privileging one area of investigation while simplifying the other is not a feasible option. This approach is likely to produc ...
This paper is concerned with the calibration and validation of a finite-element model of dry sliding wear in metals. The model is formulated within a Lagrangian framework capable of accounting for large plastic deformations and history-dependent material b ...
A consensus is emerging that discontinuous shear thickening (DST) in dense suspensions marks a transition from a flow state where particles remain well separated by lubrication layers, to one dominated by frictional contacts. We show here that reasonable a ...
