Paper Abstract

We study the magnetomechanical behavior of two-phase composites containing randomly dispersed ferromagnetic particles and nonmagnetic matrix. Starting from Green's functions we investigate the magnetic and elastic fields for two particles embedded in the infinite domain and define pair-wise interaction between particles. Macroscopically, we derive the averaged stress and strain fields over the composite and two phases. We then present effective magnetostriction and elasticity of composites and simulate the magnetomechanical coupling behavior during combined magnetomechanical loading conditions. Simulations are compared with other methods and experimental data to demonstrate the capability of the proposed method.
