In this paper, a number of problems fundamental importance in piezoelectric-piezomagnetic composite material are solved. The covered range from the derivation analytical expressions for magneto-electro-elastic Eshelby tensors to analysis magnetoelectric coupling effect which is new property exhibited composite. particular, when both matrix and inclusions transversely isotropic with different moduli, shapes elliptic cylinder, circular disk, ribbon, closed-form solutions coefficientS presented...

A unified method based on the inclusion formulation is proposed to determine magnetic, electric, and elastic fields in a composite with piezoelectric piezomagnetic phases. The reinforcements are treated as ellipsoidal inclusions that enable reinforcement geometries ranging from thin flakes continuous fibers. Utilizing method, magneto-electro-elastic tensors analogous Eshelby for obtained. With these tensors, around well concentration factors determined. Furthermore, upon Mori–Tanaka...

Coupled magnetic-mechanical-electric effects involving linearly and nonlinearly coupling interactions in ferroic composites are investigated using a Green's function technique. We use the theory to suggest possible giant magnetoelectric effect ferroelectric poly(vinylidene fluoride-trifluorethylene) copolymer filled by magnetostrictive rare-earth--iron alloy particles, which is markedly larger than that best known materials. The flexible composite expected exhibit large magnetostriction. Our...

The magneto-electro-elastic Eshelby tensors that represent the stress, electric displacement, and magnetic induction in an inclusion resulting from constraint of surrounding matrix piezomagnetic-piezoelectric composites are presented. provide basis for analysis response have numerous applications such as to study defects, overall properties multiphase composites, fracture mechanics, etc. For a three-dimensional transversely isotropic piezoelectric/piezomagnetic composite containing...

The vehicle positioning system is a key component in functions such as guidance, driver alert and assistance, automation. Since installing low-cost global (GPS) or inertial navigation (INS) unit becoming common practice applications, its involvement guidance safety deserves closer investigation. Typical applications require high reliability, low cost, sufficient accuracy under all operational conditions. For GPS-based positioning, urban driving with complicated maneuvers, frequent GPS...

Tone-burst-like narrow-band surface waves are generated in the thermoelastic regime by illuminating of a solid with an array laser-generated line sources. The laser is formed system lenses and optical diffraction grating that provide for flexible easy control line-array parameters. It shown experimentally, consistent theory, generation can be controlled adjusting parameters such as number sources array, width each source, separation distance between them. Certain optimum conditions...

Different microstructures significantly affect the acoustic performance of MEMS capacitive microphones, particularly in key specifications interest. This paper presents several microstructures, including rib-reinforced backplates, suspended diaphragms, and outer vent holes. Three microphone designs were implemented to analyze impact these microstructures. Equivalent circuit models corresponding each design constructed simulate such as sensitivity, signal-to-noise ratio (SNR), low corner...

In this paper, we propose an efficient timing-driven global router, TIGER, for gate array and standard cell layout design. Unlike other conventional routing techniques, interconnection delays are modeled included during the rerouting process in order to minimize maximum channel density arrays or total track number cells, as well satisfy timing constraints TIGER. The problem is formulated a multiterminal, multicommodity network flow with integer flows under additional constraints. Two novel...

The performance of a miniature loudspeaker used in computer, communication, and consumer electronics products is an integrated function with coupled magnetic, electrical, mechanical, acoustical fields. Through the finite element method, optimal design parameters to enhance are obtained. sound pressure response simulated by using equivalent circuit method. Its electrical driver, mechanical motion, radiation analogized their elements individually. For present work, such analysis carried out...
