Utilizing the stress formulation approach a closed-form solution
is obtained for a long multi-layer cylindrical shell subjected to electro-thermo-mechanical
loads. The present analytical solution holds good to examine the elastic behaviour
of laminated composite shells with anisotropic piezoelectric layers acting as
sensor and actuator under electro-thermo-mechanical loads. Standard finite elements
are not adequate for modelling of the incompressible nature of the solid propellant
grains in rocket motors. Utilizing MSC/MARC© software, finite element analysis
has been carried out on a three-layered (solid propellant grain/insulation/metallic
casing) cylindrical shell subjected to thermal and internal pressure loads.
The structure is idealized using the eight node quadrilateral isoparametric
Hermann element for incompressible materials like propellant grain and insulation
and regular elements for casing material. The finite element analysis results
are found to be in good agreement with the present closed-form solution. This
analytical solution can serve as benchmark to finite element solutions. Stress
analysis has also been carried out on a three-layer cylindrical shell to examine
the piezoelectric effects of one of the layers as composed of piezoelectric
layers.]]>
