چکیده مقاله
Tensor analysis and an orthogonal curvilinear coordinate system
have been used to derive a complete set of equations for piezo-
magneto-elastic analysis of a functionally graded (FG) thick shell
of revolution with variable thickness and curvature. The men-
tioned structure can be subjected to mechanical, electrical and
magnetic fields. It was assumed that all material properties (me-
chanical, electrical and magnetic properties) change functionally
throughout the three axis of employed coordinate system. Kinetic
and potential energies of the system have been evaluated in order
to constitute the functional of the system. Final partial differential
equations of the system can be derived by using minimization of
the energy functional with respect to five employed functions of
the system. For validation, the obtained differential equations have
been reduced to two previously studied problems i.e. functionally
graded piezoelectric materials and functionally graded piezo-
magnetic cylinders. Furthermore, numerical results are evaluated
for a case study.
