EXPERIMENTAL AND NUMERICAL RESEARCH OF MAGNETOSENSITIVE ELASTOMERS

Popis výsledku v původním jazyce

This paper presents fabrication, experimental investigation and numerical simulation of magnetosensitive (MS) elastomers. Aligned magnecto-rheological elastomer composites were prepared using silicone elastomer as the matrix material and iron micro-particles as the magnetizable filler. The blend was cured under an external magnetic field. Cylindrical samples consisting of magneto-sensitive elastomers were prepared and tested in quasi-static compression to study the changes in their stiffness characteristics under the influence of a magnetic field. The basic equations of the mechanical equilibrium and Maxwell's equations arc briefly summarized and a Helmholtz strain-energy function for MS anisotropic elastomers is shown in order to govern the interaction between a magnetoelastic anisotropic material and a magnetic field. Some FEM solutions of the coupling of MS anisotropic materials and an applied magnetic field are implemented in Comsol Multiphysics.
