In this study, discrepancies between the free vibration of fiber-metal laminate (FML) and composite cylindrical shells reinforced by carbon nanotubes (CNTs) based on Love’s first approximation shell theory have been considered by beam modal function model. The representative volume elements consist of three and four phases for composite and FML structures, respectively, which include fiber, CNT...

Vaporizing foil actuator welding (VFAW), an impact method, was used for the first time to produce high strength welds between SiC-reinforced 8009 aluminum metal matrix composite (MMC) (8009/SiC/11p) and 7075 alloy (AA7075). Microscopic characterization of dissimilar weld revealed multiple heterogenous microstructural zones including unbonded zone at center, a flat interface, wavy trapped jet co...

This paper presents a 3D transmission line matrix (TLM) implementation for the solution of transient heat flow in power devices. The miniaturization of electronic networks creates problems of heat dissipation. Good thermal management is therefore essential. Simulating power electronic systems presents peculiar challenges due to the need of detailed modeling of both circuitry and control algorit...

Metal Matrix Composite (MMC) coatings of Tungsten Carbide (WC) and Nickel (Ni) powder were produced using laser cladding process. A crack free good metallurgically bonded WC-Ni coating about 5mm thick from varying both energy density percent mixture Ni WC. In this study, the microstructure characterised optical microscope (OM), scanning electron (SEM) with EDS, while mechanical properties studi...

Tungsten carbide particles reinforced metal matrix composite (MMC) coatings can significantly improve surface wear resistance owing to their increased hardness. However, the presence of macro- and micro-residual stresses in MMC have detrimental effects, such as reducing service life. In this study, neutron diffraction was used determine residual spherical fused tungsten (sFTC) Cu deposits after...

Although laser-assisted turning (LAT) has been studied for decades, little is known on the effect of bulk temperature rise and residual in workpiece. Here we report an investigation a comparison characteristics LAT Ti6Al4V alloy laser heating Al/SiC metal matrix composite (MMC) as two materials have significant differences thermal conductivities. The research shows that at low cutting speed wit...

Aluminum-based metal matrix composite (MMC) materials are used in the design of ground transportation vehicles and aircraft. Compared with conventional, unreinforced alloys, composite materials usually exhibit higher strength, both at ambient and elevated temperatures, as well as good fatigue strength and wear resistance. MMCs could be produced by variety of methods such as Stir cast, Liquid In...

Metal matrix composites are undoubtedly a group of advanced engineering materials. Compared to unreinforced matrix material, they are characterized by increased strength, greater stiffness, increased wear resistance, better mechanical properties and dimensional stability at elevated temperatures as well as lower density. Due to its very favorable tribological properties for many years research ...
