摘要：

A meshless method called the element-free Galerkin method (EFGM) is introduced into the calculation of magnetostrictive thin film. With the finite element method (FEM), the distortion of the elements will decrease the precision, so EFGM is used to solve this problem. Two different magnetomechanical coupling models are proposed and a thin film cantilever is simulated with these two modeling methods. At last, the results are compared with the experiment data to illustrate the performance of EFGM and the correctness of the models.
