Abstract

The study investigates the transient response of a cantilever Magneto-Electro-Elastic (MEE) beam subjected to thermal loading. A finite element model utilizing an eight-node quadrilateral element was developed using a FORTRAN program to integrate mechanical, electrical, and magnetic fields. This model was employed to examine the influence of stacking sequences in layered beams and volume fractions in multiphase MEE beams. To validate the accuracy of the developed model, results were compared with those from the commercial finite element software ANSYS, using a beam composed of piezoelectric ceramic material. The comparison confirmed a strong correlation between the results, ensuring the model’s reliability. Findings reveal that piezoelectric coupling significantly affects the mechanical response, while the dynamic responses of electrical and magnetic fields demonstrate complex dependencies on stacking sequences and volume fractions. These insights are crucial for understanding the dynamic behavior of layered and multiphase MEE ceramic materials, which hold great potential for application as sensors or actuators in active structural systems.
