In this paper, a microstructure-dependent magneto-electro-elastic functionally graded porous (MEEFGP) beam model is proposed using variational approach. To account for the microstructure effect, extended modified couple stress theory incorporated in new model. addition, porosity variation of two-phase through thickness direction also considered. The developed verified terms its correctness with...

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 analysis of complex systems tends to be approached through a separation and simplification the main macro phenomena and, thus, addressed dedicated techniques, tools, algorithms. A smart interesting possibility, instead, is represented by so-called model-based design analysis, which allows one interface coming from interactions different physical natures. This paper aims propose multi-physic...

This paper establishes an axisymmetric model for a levitation device. Therein, the Maxwell equations are combined with balance of linear momentum. Different possible formulations to describe MAXWELL presented and compared discussed in example. A high order finite element discretization using GALERKIN's method space generalized NEWMARK‐α time developed electro‐magneto‐mechanical approach. Severa...

In this study, two-dimensional electro-mechanical analysis of a composite rotating shaft subjected to non-axisymmetric internal pressure and applied voltage is investigated where hollow piezoelectric shaft reinforced by boron nitride nanotubes (BNNTs). Composite structure is modeled based on piezoelectric fiber reinforced composite (PFRC) theory and a representative volume element has been cons...

In this research, the effect of shape parameters such as number of magnet wire turns, spools, thickness of the gap, and pole length in a Magneto-rheological (MR) fluid damper is analytically investigated and the optimization of these parameters is done with response surface method (RSM) which is combined Neuro-Fuzzy method and Particle Swarm Optimization (PSO) algorithm. Since the electro-magne...

There has been permanent interest in investigations of new magnetic sensors and their various applications (Edelstein, 2007). Last years there is a rapid progress in development of magneto-optical sensors because of their sensitivity and potential for miniaturization. Magnetometers, based on magneto-optical sensors have high sensitivity comparable to, or even surpassing this of the SQUIDs (Supe...
