A theory of mechanical behaviour of the magneto-sensitive elastomers isdeveloped in the framework of a linear elasticity approach. Using a regularrectangular lattice model, different spatial distributions of magneticparticles within a polymer matrix are considered: isotropic, chain-like andplane-like. It is shown that interaction between the magnetic particles resultsin the contraction of an elastomer along the homogeneous magnetic field. Withincreasing magnetic field the shear modulus for the shear deformationperpendicular to the magnetic field increases for all spatial distributions ofmagnetic particles. At the same time, with increasing magnetic field theYoung's modulus for tensile deformation along the magnetic field decreases forboth chain-like and isotropic distributions of magnetic particles and increasesfor the plane-like distribution of magnetic particles.
