Abstract— Non Destructive Evaluation (NDE) is the method of evaluating material or object without to damage or make worse. This method is used in process and quality controls and it is also used to evaluate of aircraft, power plants, turbines, nuclear reactor. Electro thermal model is used to find the defects in metals, semiconductor and composite materials etc. till now research has not been t...

in this article, the bending and free vibration analysis of functionally graded (fg) nanocomposites timoshenko beam model reinforced by single-walled boron nitride nanotube (swbnnt) using micro-mechanical approach embedded in an elastic medium is studied. the modified coupled stress (mcst) and nonlocal elasticity theories are developed to take into account the size-dependent effect. the mechani...

The continuous development of modern industries rises the necessity for functionally graded materials. This research starts from consideration that incorporation SiC particles in molten aluminum alloy can be difficult due to very low wettability particles. In order increase their wettability, were covered with a layer metallic copper. into mass was performed by centrifugal casting. secondary hy...

The present work derives the exact analytical solutions for buckling and post-buckling analysis of nano-composite beams reinforced by single-walled carbon nanotubes (SWCNTs) based on the Euler-Bernoulli beam theory and principle of virtual work. The reinforcements are considered to be aligned in the polymeric matrix either unifor...

A two-dimensional (2D) subwavelength nanostructure for antireflection coating is fabricated upon a transparent substrate. Self-assembled 2D colloidal crystals are used as a nanoscale composite material with controlled thickness and low refractive index. The feature size of the structure is approximately 105 nm. The structure is used for antireflection coating, and the measured reflectivity of a...
