- Аннотация: We present the computer model of the magnetoelectric effect in two-layer structure based on magnetorheological elastomer and piezoelectric PVDF layer. The effect is based on the assumption about the displacement of magnetic particles inside the elastic matrix under the external gradient magnetic field and the formation of chain-like structures. Such displacement causes magnetorheological layer deformation. This deformation leads to corresponding bending of PVDF layer, which results in induced voltage from the sample. To calculate particle redistribution and corresponding bending of the system molecular dynamic approach was used. To calculate particles positions Verlet integration [1] was used. We considered dipole-dipole model for particle-particle interaction and “springs” [2] model for particle-matrix elastic interaction. In the model the magnetorheological system consists of around 1000 iron particles which are considered as isotropic and anisotropic samples varying with concentration of magnetic filler, size and space distribution of particles, elastic properties of the matrix, linear dimensions of the sample. For simulation of the presented model and visualization of the system tool was designed using C++ and Python programming languages. Presented model can be used to study these novel functional materials, analyze their features and predict the optimal composition of such composites for further profound experimental study.
