ABSTRACT This study examines the thermo‐electro‐elastic responses of a long hollow cylindrical piezoelectric material due to pulse heating flux on its surface. Formulations suggested by Lord and Shulman for generalized piezothermoelastic systems are used. The response vessel is modeled under axisymmetric conditions, leading formulation three coupled governing equations: motion, Maxwell energy formulations. finite element approach used solve these equations numerically. Newmark time‐marching methodology derive temporal evolution. presentation novel numerical results provides insights into dynamic behaviors cylinder transient heat settings. relaxation time coupling between mechanical, thermal electrical fields highlighted in this work, providing useful.
