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.
