Magneto-caloric materials offer the possibility to design environmentally friendlier thermal management devices compared widely used gas-based systems. The challenges develop this solid-state based technology lie in difficulty of finding presenting a large magneto-caloric effect over broad temperature span together with suitable secondary application parameters such as low heat capacity and hig...

In this study, the dispersal caused by transverse Poisson’s effect in a magneto-electro-elastic (MEE) circular rod is taken into consideration using nonlinear longitudinal wave equation (LWE), mathematical physics problem. Using generalized exp-function method, we investigate families of solitary solutions one-dimensional LWE. computer program Wolfram Mathematica 10, these new exact and LWE are...

Multiferroic composites with ferromagnetic and ferroelectric phases have been studied in recent years for use as sensors of AC and DC magnetic fields. Their operation is based on magneto-electric (ME) coupling between the electric and magnetic subsystems and is mediated by mechanical strain. Such sensors for AC magnetic fields require a bias magnetic field to achieve pT-sensitivity. Novel magne...

The size-dependent longitudinal and torsional dynamic problems for small-scaled rods have importance in two-phase media. special case of the elastic rod equation such as magneto-electro circular are seen literature commonly, but this work, generalized form nonlinear equation, which was not studied literature, is considered. exact solutions obtained via Mathieu approximation method with a novel ...

The magneto-electro-elastic (MEE) material under thermal environment exhibits pyroelectric and pyromagnetic coefficients resulting in pyroeffects such as pyroelectric and pyromagnetic. The pyroelectric and pyromagnetic effects on the behavior of multiphase MEE sensors bonded on the top surface of a mild steel plate under thermal environment is presented in this paper. The aim of the study is to...

The linear piezoelectric and nonlinear hysteresis behaviors of ferroelectrics are well-known have been extensively studied. However, less attention has paid to the variations their mechanical properties under electric loading. In this work, using tube cylinder specimens, three independent elastic coefficients related internal frictions PZT-5H ferroelectric ceramics measured our proposed modifie...

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...
