Abstract
Magneto-electro-elastic (MEE) materials under thermal environment exhibits pyroelectric and
pyromagnetic coefficients resulting in pyroeffects such as pyroelectric and pyromagnetic. The pyroeffects on
the behavior of multiphase MEE sensor bonded on top surface of a mild steel cylindrical shell under thermal
environment is presented in this paper. The study aims to investigate how samples having different volume
fractions of the multiphase MEE sensor behave due to pyroeffects using semi-analytical finite element
method. This is studied at an optimal location on a mild steel cylindrical shell, where the maximum electric
and magnetic potentials are induced due to these pyroeffects under different boundary conditions. It is
assumed that sensor and shell is perfectively bonded to each other. The maximum pyroeffects on electric and
magnetic potentials are observed when volume fraction is vf = 0.2. Additionally, the boundary conditions
significantly influence the pyroeffects on electric and magnetic potentials.
