چکیده
|
In this research, static stresses analysis of boron nitride nano - tube reinforced composite (bnntrc) cylindermade of poly - vinylidene fluoride (pvdf) subjected to non - axisymmetric thermo - mechanical loads and appliedvoltage is developed. the surrounded elastic medium is modelled by pasternak foundation. composite structureis modeled based on piezoelectric fiber reinforced composite (pfrc) theory and a representative volume elementhas been considered for predicting the elastic, piezoelectric and dielectric properties of the cylinder. higher ordergoverning equations were solved analytically by fourier series. the results demonstrated that the fatigue life ofbnntrc cylinder will be significantly dependent on the angle orientation and volume fraction of bnnts. resultsof this investigation can be used for the optimum design of thick - walled cylinders under the multi - physical fields.
