Summary: Stretchable materials like elastomers and hydrogels are prone to crack growth during repeated stretching. Current methods to improve fatigue resistance involve blocking cracks with high-energy phases, which are often limited to specific polymers or compromise other properties. In this study, we challenge this concept and demonstrate the crack bridging effect in micropatterned elastomers, where micropatterns shield polymer chains by bridging behind the crack front. By creating composites with molecularly separated fibers and matrices, we achieve a fatigue threshold three times higher than traditional composites based on high-energy strategies. This crack bridging strategy has general usefulness and does not rely on specific materials for inter- and intra-polymer interactions.

Summary: The preparation of nanocomposites with controllable structure is important, and the preparation of ultrashort composite nanotubes with core-shell structure from long nanotubes is challenging. Researchers have successfully prepared ultrashort core-shell composite nanotubes with the outer layer of SiO2 or TiO2 and the inner layer of sulfonated PDVB by mixing their long composite nanotubes with polymer resin and shearing at a high strength with a twin-screw extruder.

Summary: The novelty of this study lies in constructing an Entropy-based wear and fluid-solid-thermal (FST) coupled model for journal bearings, and revealing the transient interaction behavior between wear evolution and FST evolution during repeated starting and stopping. The wear rate is measured experimentally, and the contact temperature, friction coefficient and normal contact force are obtained from the validated FST model. Wear tests and numerical calculations are conducted to validate the predicted wear rate and investigate the time-varying wear and FST evolution of journal bearings.

Summary: A polymer coating prepared by liquid spraying technology on the surface of 20CrMo steel demonstrates good tribological and anti-cavitation erosive properties. It can effectively replace CuPb24Sn copper alloy in valve plates for pumps under different lubrication conditions. The coating exhibits adhesive wear and reduces frictional loss, and mainly shows abrasive wear under complex working conditions. Its lipophilicity, high hardness to elastic modulus ratio, and corrosion resistance are the main influencing factors for its performance.

Summary: This study simulated the rolling contact of a driving wheelset over tangent and curved tracks at a speed up to 500 km/h using an explicit finite element approach to derive creep curves. The comparison between quasi-steady curves and transient curves in the presence of rail corrugation helped to identify cases where traditional theories are inapplicable and where transient effects must be considered. Additionally, the study further analyzed the influence of middle/high-frequency vibrations in the presence of rail corrugation.

Summary: The influence of high-carbon addition on the microstructure, hardness, and wear behavior of CoCrNi alloy was investigated. It was found that the addition of carbon resulted in the formation of carbide particles, enhancing the hardness and improving the wear resistance. Fracture and detachment of hard carbides during friction introduced additional abrasive particles, transitioning the wear mechanism from adhesive-dominated to abrasive-dominated.
