Adhesion, Friction, and Surface Interactions

Air permeability is a key property of knitted fabrics that directly influences thermal and moisture comfort, particularly in sportswear, innerwear, and outerwear applications. In this study, air permeability values of 21 knitted fabric samples—differing in yarn count, twist level, knit structure, and fabric density—we…

Wear mechanism is important since it leads to revisions in Total Hip Replacement (THR) surgeries. Contact pressure plays an important role in wear mechanisms and needs to be investigated in detail to obtain more accurate wear predictions to understand the wear performance of the implant in the design stage. This study…

PURPOSE: The objectives of the current study were to evaluate and compare the retention loss and wear rates of locater attachments made of three different materials under cyclic load. MATERIALS AND METHODS: Three locater attachments, including those made of titanium nitride-coated (conventional Locator), titanium carb…

Abstract This study investigated surface roughness, the wettability behavior, and surface energy of Co-based alloy specimens textured using the biomimetic Laser Surface Texturing (LST) method. The surface texture was inspired by the patterns found on marine shells. The impacts of the parameters on wettability, Surface…

This study aimed to understand the collision characteristics of different soccer balls by determining energy dissipation (ED) during collisions. Soccer balls from five different brands were kicked towards a framed tempered glass. The kicks were performed with the balls inflated under three inner pressure conditions. T…

Frictional sliding instability, commonly manifested as stick-slip, is of broad interest in seismology, physics, chemistry, and engineering. Although surface roughness is recognized as a key factor influencing the transition from steady sliding to stick-slip, its precise role in controlling frictional stability remains…
