The critical thickness of structural transition from a tetragonal structure to a normal bulk structure for epitaxial ultrathin films deposited on the metallic and semiconductor substrates is thermodynamically considered. It is found that equilibrium between the elastic energy of the tetrahedral...

The literature indicates that a 20% reduction in the weight of empty 40-foot shipping containers would result in $28 billion of fuel savings, along with a 3.6 exajoule reduction in the energy demand over containers' 15-year lifetime. Decreasing the energy demand and thereby greenhouse gas...

TiC and TiB2 reinforced iron based metal matrix composite (MMC) coating was synthesized on mild carbon steel by laser cladding employing B4C, ferrotitanium, and FeCrSiB mixed powders. The microstructure and chemical composition were analyzed by means of SEM, EPMA, and XRD. Results show that the...

This work presents the theoretical aspects of a one dimensional computational approach for the determination of the cross sectional stiffness of composite rotor blades. The method is based on a vector variant of the classical lamination theory embedded into a geometrically exact large...

В статье рассмотрена возможность получения композиционных материалов на основе металлического никеля и сверхтвердых материалов. Установлено, что такой...

The article considers a possibility of making composite materials from metal nickel and super-hard materials. It shows that such a product is available in the world market, but there is no information on technology of manufacture of such a product in open literature. It sets the issue of...

A review of structural health monitoring methods, including residual cure strain monitoring is presented for the wind turbine blade industry. A comparison is presented for dielectric, acoustic, ultrasonic, thermal and fibre optic monitoring methods. This review highlights the need for further...

In this paper the harmonization of new wind turbine rotor blades development is given as well as the analysis of behavior by verification testing for a wind turbine rotor blade of composite materials. The design, fabrication, the status of wind energy standards and the analysis of behavior by...
