ClearA numerical model to simulate the transient frictional viscoelastic sliding contact
This paper develops a numerical model for transient sliding contact between viscoelastic surfaces, accounting for friction and partial slip. It is a mechanical engineering study with no connection to microplastics and is a false positive for microplastic relevance.
A Fully Coupled Normal and Tangential Contact Model to Investigate the Effect of Surface Roughness on the Partial Slip of Dissimilar Elastic Materials
Researchers developed a fully coupled contact mechanics algorithm using a global shear traction search method to model partial-slip behavior between elastically dissimilar materials with rough surfaces. They found that surface coupling produces a non-linear relationship between the stick-area ratio and tangential load, with higher RMS gradient or lower RMS roughness surfaces retaining more stick regions under low-to-medium loading conditions.
Multiscale Modeling of Friction Coefficients: A Review from Nanocontacts to Macroscopic Sliding
This review examines multiscale modeling approaches for friction coefficients from atomic nanocontacts to macroscopic sliding behavior, finding that classical Coulomb and Amontons laws underrepresent the complexity of friction phenomena revealed by modern computational and experimental research.
Theoretical Study of the Friction Coefficient in the M-B Model
This paper derived new mathematical expressions for friction coefficients in a fractal-based surface contact model, addressing how microscopic surface roughness affects macroscopic friction behavior. The model improves predictions of friction for engineering applications where surface texture matters. Better friction models contribute to more durable and efficient mechanical systems.
Formation and changing principle of the dynamic shape of the pitch polishing lap under the loading conditioner in continuous polishing
Researchers investigated the formation mechanism and dynamic shape changes of a pitch polishing lap under loading conditioner conditions during full-aperture continuous polishing of large flat optical elements. The study modeled the viscoelastic behavior of the pitch lap to understand how its surface figure evolves during polishing and its effect on the resulting optical surface quality.
Modeling droplet-particle interactions on solid surfaces by coupling the lattice Boltzmann and discrete element methods
Researchers developed a numerical method coupling the lattice Boltzmann method for two-component fluid dynamics with the discrete element method for contact forces to model droplet-particle interactions on solid surfaces, accounting for particle wettability and friction. The coupled LBM-DEM approach enables simulation of interfacial flows with frictional solid particles relevant to microplastic transport modeling in porous and surface environments.
Time-Dependent Contact Behaviour of ZDDP-Derived Tribofilms: A Viscoelastic Layered Model Approach
Researchers studied how protective lubricant films (called tribofilms) formed by the common engine oil additive ZDDP behave under pressure over time, finding that these films act like a layered viscoelastic material — with mechanical properties that change depending on load duration — which matters for predicting how well engine components resist wear.
Material Response to Rolling Contact Loading
This materials science study investigates how rolling contact in ball bearings causes microplastic deformation in steel, leading to crystallographic texture changes, residual stresses, and eventual fatigue failure. The term 'microplastic' in this paper refers to small-scale plastic deformation in metals and has no connection to environmental plastic pollution.
