Particle Concentration Effect on Thermal Properties of Nano-fluids
Abstract: AbstractWith the advancement of time and system miniaturisation, requirement of high thermal capacity material is increasing. This problem can be served by nano-fluids as they have high thermal conductivity compared to the conventional materials. Nano-fluids are the suspension of solid nano-particles in the base-fluid. Water (H2O) is considered as the base-fluid in the present work while Al2O3, Cu, TiO2, SiC and B4C are considered as nano-particles. Two-phase mixture rule and …

Effect of TMT Bar Lugging on Steel Reinforcement Failure Mode under Monotonic Loading
Abstract: Thermo-mechanically treated (TMT) ribbed bars modify the overall progress of failure in reinforced concrete. The ribs maintain anchorage after friction on the rest of the bar is eliminated during deformation, taking up the ultimate compressive load. This however, is inadvertently jeopardized by the stress concentration effect of the rib geometry. This paper analyses the extent to which some of the geometric forms of bar lugging affect the prevalence of ductile …

Effect of Carbonyl Iron Particle Concentration on The Printability and Stiffness of Magnetorheological Elastomer Filaments
Abstract: Magnetorheological elastomer (MRE) are increasingly valued for their field-responsive mechanical properties, making them ideal for adaptive components in automotive, aerospace, and vibration control systems. However, conventional mould-based fabrication methods limit design flexibility, produce excess material waste, and are unsuitable for complex or customized geometries caused challenges that have hindered broader industrial adoption. Although 3D printing offers a compelling alternative, research on printable MRE filaments remains limited, particularly regarding how carbonyl …
