Abstract: The paper deals with theoretical study of shear and tensile elastic properties of ferrogels filled with magnetizable particles, united in linear chains, percolating the sample. It is supposed that a magnetic field is applied along the chains, perpendicular to the shear and parallel to the tension. Our results show that at a certain threshold deformation the chains are ruptured; this break leads to a jump down of the macroscopic stress. This effect is observed for both types of the deformation. The results of calculations are in agreement with experimental data.
