Magnetic field-induced, reversible martensitic transformations in NiCoMnIn meta-magnetic shape memory alloys were studied under constant and varying mechanical loads to understand the role of coupled magneto-mechanical loading on the transformation characteristics and the magnetic field levels required for reversible phase transformations. The samples with two distinct microstructures were test...

In this article, the influence of important parameters on size-dependent thermoelastic behavior functionally graded magneto-electro-thermo-elastic microcylinders (FGMEE) is studied by means modified stress couple theory and under combined mechanical-thermal-magnetic loads. The equations motion were derived considering linear shells first-order nonlocal shear deformation shells. following, resul...

A unified thermodynamic framework for the characterization of functional materials is developed. This framework encompasses linear reversible and irreversible processes with thermal, electrical, magnetic, and/or mechanical effects coupled. The comprehensive framework combines the principles of classical equilibrium and non-equilibrium thermodynamics with electrodynamics of continua in the infin...

The last fifteen years many European countries have integrated large percentage of renewable energy on their electricity generation mix. In Denmark the 21.3% of the electricity consumed nowadays is produced by the wind, and it has planned to be the 50% by 2025. In order to front future challenges on the power system control and operation, created by this unstable way of generation, Demand Side ...

To improve the durability of lead free solder joints under high strain rates, such as drop and shock loading, some area array manufacturers have converted to low silver (Ag) content tin silver copper (SAC) solder spheres instead of the commonly accepted SAC305 solder. While the lower silver content SAC solder joints may address high strain rate shock loads, the durability of these joints under ...

Transmission of high power at high voltages over very long distances has become very imperative. At present, throughout the globe, this task performed by overhead transmission lines. The dual task of mechanically supporting and electrically isolating the live phase conductors from the support tower is performed by insulators. The electrical potential, field and temperature distribution along th...

Using harmonic differential quadrature (HDQ) method, nonlinear vibrations and instability of a smart composite cylindrical shell made from piezoelectric polymer of polyvinylidene fluoride (PVDF) reinforced with boron nitride nanotubes (BNNTs) are investigated while clamped at both ends and subjected to combined electro-thermo-mechanical loads and conveying a viscous-fluid. The mathematical mode...

This review examines the use of magneto-acoustic methods to measure electrical conductivity. It focuses on two techniques developed in last decades: Magneto-Acoustic Tomography with Magnetic Induction (MAT-MI) and Magneto-Acousto-Electrical (MAET). These developments have potential change way medical doctors image biological tissue.
