Magnetic field effects on the elastic behavior of polymeric piezoelectric cylinder reinforced with CNTs

Magnetic field effects on the elastic response of polymeric piezoelectric cylinder reinforced with carbon nanotubes (CNTs) is studied. The cylinder is subjected to internal pressure, a constant electric potential difference at the inner and outer surfaces, thermal and magnetic fields. The Mori-Tanaka model is used for obtaining the equivalent material properties of the cylinder. Based on the charge and equilibrium relations, the governing differential equation of the cylinder is derived and solved analytically. The main purpose of this paper is to investigate the effect of magnetic field on the stresses, the electric potential and radial displacement distributions of the polymeric piezoelectric cylinder. The presented results indicate that considering magnetic field can reduce the stresses of nano-composite cylinder
