Abstract: This paper presents a complete analytical solution for transient responses of a transversely isotropic thermopiezoelectric finite composite cylinder under axisymmetric boundary conditions. The governing equations for coupled axisymmetric electro-thermo-mechanical field of a transversely isotropic piezoelectric medium are employed, and the corresponding general solutions are derived. A boundary-value problem corresponding to composites of finite thermopiezoelectric cylinder with axisymmetric mechanical and electrical loadings applied at the curve surface of a cylinder is solved. The solutions presented in this study can provide fundamental understanding of thermo-electro-mechanical behaviour of thermopiezoelectric finite composite cylinder under various loading conditions, and are useful for the development of piezocomposites for practical applications.

Abstract: An elliptical crack subjected to uniform temperature gradient in an infinite thermopiezoelectric solid is investigated in this work. Theoretical attempt has been made to find the temperature and piezoelectric fields at first by using a potential function formulation. The field intensity factors due to the thermal disturbance are obtained, as well as the local fields of the stresses and electric displacements near the crack front.
