Abstract-The magneto-electro-elastic (MEE) material under thermal environment exhibits pyroelectricand 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 investigate how samples having different volume fractions of the multiphase MEE sensor behave due to pyroeffects using finite element method. This is studied at an optimal location on the plate, where the maximum electric and magnetic potentials of the MEE sensor are induced due to pyroeffects under various boundary conditions. It is assumed that plate and sensor are perfectly bonded to each other.The maximum pyroelectric and pyromagnetic effects on electric and magnetic potentials are observed when volume fraction is v f = 0.2. Additionally, the boundary conditions significantly influence the pyroelectric and pyromagnetic effects on electric and magnetic potentials of the sensor.

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 method. Design/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 studied. Findings -The critical buckling temperature is higher for MEE axisymmetric cylinder as compared to elastic cylinder. Originality/value -Linear thermal buckling and vibration analysis of MEE axisymmetric cylinders are studied using the finite element approach. The structure can be used for active vibration control, sensors and actuators. Studying the buckling and vibration behaviour of such structures and influence of coupling effect is extremely useful for the design of magnetoelectroelastic structures.

In this paper the static, transient and free vibration analysis of a thermo-magneto-electric-elastic solid cylinder is analyzed stochastically by using hybrid numerical method (combined finite element and Newmark finite difference method).An infinite solid cylinder made up of 6mm class considered. The constitutive equations containing the mechanical, magnetic, electrical and thermal fields and investigated by free and forced Vibirational boundary conditions. The transient finite element equations are obtained by assumed shape functions. After assembling the Mass, Stiffness and Damping and matrices, the global dynamic equations are in the form of time field. The resulting equations are solved by using the finite difference technique with suitable time instants. By using material constants values the displacement, velocity and acceleration of vibrations are obtained with various time values and the non dimensional frequencies are also obtained by different values of non dimensional wave number. Numerical work is carried out by the electric and magnetic materials Cdse and CoFe2o4. The outcomes are tabulated and represented graphically.
