Special Issue Information

Dear Colleagues,

Wear on materials predominantly contributes to the degradation and failure of mechanical systems. The lack of understanding of wear is explicable due to the challenges in simulating and characterizing wear phenomena effectively for different tribological conditions, especially given the synergistic and transient nature of wear. The limitations range from analysis of worn specimens to developing lab-scale experiments and multiscale wear models, replicating tribogical systems.

Analyzing and modelling wear requires the characterization of worn specimens. This necessitates quantifying wear using instrumented methods like microscopy and spectroscopy.

Because of the multiscale and multiphysical nature of wear, wear models may be mesh- or particle-based, (semi-) analytical or probabilistic, and/or employ hybrid methods. It is important that wear models have a physical basis and are validated experimentally.

The scope of this Special Issue will include research work on experimental wear characterization and numerical wear models. The research approach taken can employ related studies on contact mechanics, surface engineering, as well as frictional and lubrication. Of interest are numerical and experimental methods to simulate and analyze complex wear phenomena such as three-body abrasive wear, surface fatigue, adhesive wear, fretting, tribochemical wear, erosion, and lubricant wear.

When a slurry TBM advances in pebble and rock strata, large rock particles are carried in pipelines out of a tunnel by moving slurry. To estimate the wear of horizontally straight slurry discharge pipes, a phenomenological model was proposed that was mainly based on knowledge gained by means of direct and indirect in situ observations. The proposed model applies an equation composed of three variables, namely, the wear rate (λ), the central angle (2α), and the excavated tunnel length (L), to estimate the wear distribution along a pipe’s internal surface. The results indicated that wear mainly occurred on the bottoms of pipes. In addition, linear relationships between the maximum pipe wear amount (δmax) and the excavated tunnel length (L) were found for specific pipes and specified types of ground. The observed wear rates of different pipes in different types of ground had varied constants. The wear rates were higher for pipes in rock ground than for those in a pebble layer. For horizontally straight pipes, the observed wear rates were 0.0045 mm/m in a pebble layer and 0.0212 mm/m in rock ground. Lastly, to improve the proposed model, more field monitoring will be necessary to determine the pipe wear rates in different types of ground in the future. Full article
