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, thermo-nonlocal vibration of double bonded graphene sheet (DBGS) subjected to 2D-magnetic field under biaxial in-plane pre-load are presented. The elastic forces between layers of graphene sheet (GS) are taken into account by Pasternak foundation and the classical plate theory (CLPT) and continuum orthotropic elastic plate are used. The nonlocal theory of Eringen and Maxwell’s re...

This article documents a new implementation of a three dimensional constitutive model that describes evolution of elastic and transformation strains during thermo-mechanical shape memory alloy loading events assuming a symmetric, isotropic material response. In achieving this implementation, improvements were made to the original formulation of the constitutive model. These improvements allow f...

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 recent years, impedance measurement method by piezoelectric (PZT) wafer activesensor (PWAS) has been widely adopted for non-destructive evaluation (NDE). In this method, theelectrical impedance of a bonded PWAS is used to detect a structural defect. The electro-mechanicalcoupling of PZT materials constructs the original principle of this method. Accordingly, the electricalimpedance of PWAS c...

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...

Piezoelectric materials are widely fabricated and investigated for potential applications in microelectromechanical systems as direct converters between mechanical electrical signals, where some show pyroelectric features involving thermo-electro-mechanical interactions. This study aimed to introduce a novel numerical technique predict the behaviors of piezoelectric structures, based on strong-...
