Magneto-mechanical coupling of smart composites with chain-structured magnetostrictive particles
Magneto-mechanical coupling behavior is investigated for smart composites containing chainstructured magnetostrictive particles under both magnetic and mechanical loading.A representative volume element containing a chain of infinite particles is introduced to solve averaged magnetic and elastic fields in the particles and the matrix based on the Green’s function technique.Effective behavior of smart composites is estimated by considering the particle’s magnetic interaction force and particle-particle mechanical interaction.Magnetic-field-dependent,transversely isotropic effective elasticity of composites is derived explicitly.Comparisons of model results with the experimental data and other models show the efficacy of the model and suggest that the particle interactions have a considerable effect on the effective magneto-elastic properties of composites
