Prompt Description

Generate a graphical abstract for a mechanical engineering/tribology journal. Left: Schematic diagram of elastohydrodynamic lubrication of a steel-polymer textured bearing, with a smooth rigid steel surface above, a UHMWPE polymer surface with circular dimple textures below, and a lubricating oil film in the middle, labeled with film thickness h(x,y), and an arrow indicating the sliding direction U. Middle: Comparison of traditional elasticity models and Cosserat elasticity models. Traditional models include only displacement deformation; Cosserat models include displacement and micro-rotation, showing couple stress and Cosserat characteristic length l, and arrows indicating the coupling of the Reynolds equation and the Cosserat elasticity equation. Right: Simplified trend chart showing that increasing the Cosserat characteristic length leads to increased load-carrying capacity, decreasing the texture spacing along the sliding direction enhances size effects, and the texture diameter has a more significant impact on the pressure gradient than the texture depth. The overall style is simple, academic, vectorized, in blue-gray tones, and suitable for high-level academic journal graphical abstracts.
