Numerical simulation is rarely used for magnetoelectric materials due to coupling complexity, but COMSOL software proves to be an effective tool for analyzing the changes of coefficients and vibration modes in magnetoelectric laminates. The simulation results show good agreement with theoretical analysis and experiments, indicating the potential for further nonlinear theoretical analysis.
Numerical simulation is often used for piezoelectric materials or magnetostrictive materials, but it is rarely used for magnetoelectric materials due to the coupling complexity. COMSOL multiphysics is a powerful and effective numerical simulation software package. It can not only study the influence of parameter and frequency changes, but also extract stress distribution, electric potential, vibration mode, etc. In this paper, based on the existing equivalent circuit theory of L-L mode magnetoelectric laminates, COMSOL software is used to analyze the changes of DME and CME coefficients with frequency, the frequency curves of different proportions of magne-tostrictive materials, and the vibration modes at the frequency peaks. It is obvious that the L-L mode laminated composite vibrates along the length direction regardless of DME and CME effects. The numerical simulation results are in good agreement with the existing theoretical analysis and experimental research. The results show that this simulation method is desirable and lays a foundation for further nonlinear theoretical analysis.
