| Abstract: | This context outlines a basic view of the torsional behaviors through the application of various piezoelectric actuator and sensor layers in the laminated composite rectangular bar subjected to uniform thermal loading with considering the pyroelectric effect. The structure with the Saint-Venant torsion theory is modeled with the prismatic torsion formulations under applied mechanical torsion loading and then the results are presented to visualize the states of the torsional stiffness and the significance of the thermal field. In the current study, an analytical method for determining the pyroelectric effect and the control gain with the lamination angle dependence for the torsion angle is presented. The effect of one piezopolymer and two piezoceramic plates on the torsion angle considering the different number of layers and stacking sequence in the long laminated composite bar subjected to torsional torque are studied. The torsion angles are increased and decreased through the application of the electric control gain by the piezoelectric layers attached to the surface of the composite bar. The Abaqus software package is used to create a numerical model validation of the laminated composite bar without considering the pyroelectric effect. Results are presented to illustrate the pyroelectric effect and demonstrate its efficiency and accuracy. [ABSTRACT FROM AUTHOR] |
