Abstract :
In this research, static stresses analysis of boron nitride nano - tube reinforced composite (BNNTRC) cylinder
made of poly - vinylidene fluoride (PVDF) subjected to non - axisymmetric thermo - mechanical loads and applied
voltage is developed. The surrounded elastic medium is modelled by Pasternak foundation. Composite structure
is modeled based on piezoelectric fiber reinforced composite (PFRC) theory and a representative volume element
has been considered for predicting the elastic, piezoelectric and dielectric properties of the cylinder. Higher order
governing equations were solved analytically by Fourier series. The results demonstrated that the fatigue life of
BNNTRC cylinder will be significantly dependent on the angle orientation and volume fraction of BNNTs. Results
of this investigation can be used for the optimum design of thick - walled cylinders under the multi - physical fields.
