Summary: Through atomistic simulation, the mechanical behavior of cellulose-cellulose nanocrystal hydrophilic interface was studied, showing the central role of interfacial hydrogen bonds in explaining various findings. The friction force generated by a single hydrogen bond was estimated to be around 1.3 E-10 N under a shearing speed of 1 m/s.

Summary: This paper investigates the mode-coupling friction-induced instability and stick-slip self-excited vibration of a marine stern water-lubricated rubber bearing-shaft system using the analytical method. A 2-DOF simplified theoretical model is developed to characterize the system and complex eigenvalue analysis is conducted to analyze the instability behaviors. Analytical expressions for stick-slip vibration amplitude are derived and validated through numerical integration. Parameter discussion reveals the influence of various factors on the self-excited vibration amplitudes. The findings highlight the importance of choosing proper parameter values to control the friction-induced vibration.

Summary: The study investigates the peeling and sliding behaviors of graphene nanoribbons on a graphene substrate, revealing rich dynamics in adhesion, friction, and deformation patterns. Different types of strain solitons are identified during the stick-slip sliding process, depending on the ribbon structure. The study also highlights the influence of constrained displacements on the sliding force and the quasi-linear relationship between ribbon width and sliding friction.

Summary: Studying the evolution of interface contact state and revealing the black box behavior in interface friction, as well as establishing a more accurate friction model, are crucial for improving the prediction accuracy of mechanical system performance. This study proposes a visual analysis technology based on the principle of total reflection to study interface contact behavior. By considering the dynamic variation of stress distribution in interface contact, the nonlinear characteristics of contact parameters during different stages of the stick-slip process are analyzed using experimental technology. Based on these findings, an improved stick-slip friction model is presented, which considers the change of tangential stiffness and friction coefficient caused by stress distribution variation. The simulation results of this improved model show good agreement with experimental data. This research is valuable for enhancing the prediction accuracy of mechanical system performance.

Summary: This paper presents a novel implementation of the traditional node-to-node Coulomb contact-friction problem using run-time parameter updates on conventional elasto-plastic elements. The proposed method defines two-noded elements with independent uniaxial force-deformation relations in each degree of freedom. Parameters that control the frictional interface responses are updated based on contact detection, eliminating the need for modifying the finite element library. The proposed algorithm can be applied to different cases and validated with closed-form solutions and experimental results.

Summary: In this study, the influence of shearing rate on the tangential contact behavior of smooth flat quartz surfaces with different gouges was examined through micromechanical-based experiments. The results showed significant changes in stick-slip instability with decreasing shearing rate, as well as variations in tangential stiffness and friction behavior based on the type of gouge particles. The study provides insights into the frictional behavior of different gouges under different shearing rates and the stick-slip instability at a microscopic scale.

Summary: The study found that quartz gouge exhibits unstable stick-slip behavior under high σn conditions, while slow-slip is more prevalent under low σn conditions. Localization and instability are mainly promoted by high effective normal stress and small grain size.

Summary: The computational study on the atomic-scale stick-slip friction of monolayer graphene on a copper substrate reveals a strong temperature dependence of friction force and friction mode. The role of Moire superlattices in affecting friction force is significant, especially at different temperatures, leading to changes in friction behavior and transition from athermal to thermally activated friction modes.

Summary: Regardless of surface roughness or compression, the stress relaxation of microcontacts is the same as that of bulk material. Friction is not always proportional to the contact area. This allows us to predict frictional aging of rough interfaces based on the bulk material properties of two typical polymers: polypropylene and polytetrafluoroethylene.

Summary: This study investigates the stick-slip phenomena at a low-velocity range and explores the effect of brake pad size on friction instability. The results show that smaller pads exhibit higher stick-slip amplitudes within narrower velocity ranges. Friction levels are influenced by the total contact plateau area, while the stick-slip amplitudes are affected by the size of high-pressure plateaus. The pronounced stick-slip with small pads is attributed to the presence of large high-pressure plateaus, which increase static friction.

Summary: In this study, researchers have successfully recycled waste rubber using mechanochemical devulcanization technique and developed high-performance natural rubber-silica composites. The results show that the mechanical properties of the composites, including tensile strength, tear strength and elongation at break, gradually increase with the increasing content of devulcanized rubber, with the optimum level at 40%. Additionally, the developed composites exhibit superior thermal behavior and a uniform dispersion of the filler.

Summary: Atomic-scale friction measurements were conducted on a metallic glass surface in corrosive solutions using an atomic force microscope. The irregular stick-slip motion observed was attributed to the amorphous structure of the corroded surface. We found that stronger corrosion leads to a higher probability of multiple slips with larger forces, resulting in increased average friction.

Summary: The influence of different surface topography types on stick-slip behavior was investigated. Micro-dimple textures inhibit stick-slip behavior by trapping wear debris and forming effective oil film, while micro-bulge textures reduce contact area and thus decrease the propensity of stick-slip behavior.

Summary: The functionality of products is enhanced by the use of more sensors, which is particularly important for future automobiles. Integrating sensors into vehicle structures adds value, saves weight and space. The integration of sensors requires different considerations from conventional mounting and must take into account the impact of the new environment on sensor behavior.
