Abstract: Purpose – The purpose of the paper is to investigate the linear thermal buckling and vibration analysis of layered and multiphase magneto‐electro‐elastic (MEE) cylinders made of piezoelectric/piezomagnetic materials using finite element methodDesign/methodology/approach – The constitutive equations of MEE materials are used to derive the finite element equations involving the coupling between mechanical, electrical, magnetic and thermal fields The present study is limited to clamped‐clamped boundary conditions The linear thermal buckling is carried out for an axisymmetric cylinder operating in a steady state axisymmetric uniform temperature rise The influence of stacking sequences and volume fraction of multiphase MEE materials on critical buckling temperature and vibration behaviour is investigated The influence of coupling effects on critical buckling temperature and vibration behaviour is also studiedFindings – The critical buckling temperature is higher for MEE axisymmetric cylinder as compared

TL;DR: The present study is in no ways exhaustive to the methods and results observed, but it may be considered as a guide to researchers and scholars about the behavior of MEE materials, wherein critical observations and analyses’ techniques are discussed.
Abstract: Magneto-electro-elastic (MEE) materials have been receiving a special attention from the research community owing to their specialized performance and coupled behavior under thermal, electric, magnetic and mechanical loads. The possibility of prospective energy conversion means, have additionally been added to the cause of researching about these materials. Therefore, the review presented here may be considered as a topical discussion on MEE materials and structures. Through this paper, all critical concepts revolving around MEE materials are discussed in separate sections ranging from the very definition of MEE materials, their material phenomenon, types and properties, to certain fundamental theories and micromechanical models, structural analyses of MEE structures and their nano-sized counterparts, effects of various external and internal parameters and prospective applications of these materials. The present study is in no ways exhaustive to the methods and results observed, but it may be considered as a guide to researchers and scholars about the behavior of MEE materials, wherein critical observations and analyses’ techniques are discussed.

TL;DR: In this paper, two comprehensive micromechanical models for the analysis of piezo-magneto-thermo-elastic smart composite structures with orthotropic constituents are developed and applied to examples of practical importance.
Abstract: Two comprehensive micromechanical models for the analysis of piezo-magneto-thermo-elastic smart composite structures with orthotropic constituents are developed and applied to examples of practical importance. Details on the derivations of the aforementioned models are given in Part I of this work. The present paper solves the derived unit cell problems and obtains expressions for such effective coefficients as piezomagnetic, piezoelectric, elastic and many others. Of particular importance are the effective product properties, such as magnetoelectric, pyroelectric and pyromagnetic coefficients which, in general, manifest themselves in the macroscopic composite as a consequence of the interactions of the different constituents but are not exhibited by the constituents themselves as individual entities. The effective coefficients are universal in nature and once determined, can be used to examine a number of boundary value problems associated with a given composite geometry. The present work illustrates the use of the developed models and compares the results obtained with corresponding results stemming from other analytical and/or numerical models. Furthermore, results from the two micromechanical models presented here are also compared with each other. The mathematical model developed in this work can be used in analysis and design to tailor the effective elastic, piezoelectric, piezomagnetic, magnetoelectric etc. coefficients of smart composite structures to meet the design criteria of different engineering applications by a judicious selection of different geometric and/or material parameters of interest.

Abstract: A homogenization micromechanical method is employed for the prediction of the effective moduli of electro-magneto-thermo-elastic composites. These include the effective elastic, piezoelectric, piezomagnetic, dielectric, magnetic permeability and electromagnetic coupling moduli, as well as the effective thermal expansion coefficients and the associated pyroelectric and pyromagnetic constants. Comparisons between the present homogenization theory, the generalized method of cells and the Mori-Tanaka predictions are given. Results are presented for fibrous and periodically bilaminated composites.
