“…Such magnetotunable stiffness enables MREs in a variety of applications as variable stiffness bushings (Lerner, 2005), engine mounts (Ginder, 1996) and releasable attachments (Ottaviani et al, 2006) used in the automotive industry; tunable vibration absorbers and damping components (e.g. Ginder et al, 2000;Deng et al, 2006;Lerner and Cunefare, 2008;Hoang et al, 2011), and noise control devices (Farshad & Roux, 2004). The behavior that the stiffness of MREs increases under a magnetic field is usually reffered to as MR effect.…”

“…Such property enables MAEs in applications where tunable stiffness is required, such as in vibration dampers (Deng et al, 2006;Li et al, 2012), vibration control for earthquake (Ni et al, 2010) and noise barrier (Farshad, 2004). The MR effect is usually attributed to the magnetic dipolar interaction between the adjacent particles (Jolly et al, 1996;Davis, 1999).…”

A nonlinear magnetoelastic tube under extension and inflation in an axial magnetic field: numerical solution

In the context of nonlinear magnetoelasticity theory very few boundary-value problems have been solved. The main problem that arises when a magnetic field is present, as compared with the purely elastic situation, is the difficulty of meeting the magnetic boundary conditions for bodies with finite geometry. In general, the extent of the edge effects is unknown a priori, and this makes it difficult to interpret experimental results in relation to the theory. However, it is important to make the connection between theory and experiment in order to develop forms of the magnetoelastic constitutive law that are capable of correlating with the data and can be used for making quantitative predictions. In this paper the basic problem of a circular cylindrical tube of finite length that is deformed by a combination of axial compression (or extension) and radial expansion (or contraction) and then subjected to an axial magnetic field is examined. Such a field cannot be uniform throughout, since the boundary conditions on the ends and the lateral surfaces of the tube would be incompatible in such circumstances. The resulting axisymmetric boundary-value problem is formulated and then solved numerically for the case (for simplicity of illustration) in which the deformation is not altered by the application of the magnetic field. The distribution of the magnetic-field components throughout the body and the surrounding space is determined in order to quantify the extent of the edge effects for both extension and compression of the tube.

“…One of the main applications of this theory is the mathematical modelling of magnetoand electro-sensitive elastomers, which has been studied in detail by, for example, Dorfmann and Ogden [2][3][4][5][6], Kankanala and Triantafyllidis [7] and Steigmann [8]. Magento-and electro-sensitive elastomers are considered very interesting materials, because their properties can be tuned by applying an external magnetic or electric field [9][10][11][12][13].…”

The mathematical modelling of the behaviour of magneto-sensitive (MS) elastomers is complicated due to the strong nonlinear coupling of the mechanical and electromagnetic responses. An additional problem is that one needs to consider the surrounding space in the calculation of the electromagnetic fields. Finding appropriate and simple variational formulations is an important step towards solving the governing equations using numerical methods. Variational formulations for a number of boundary-value problems are given, and different possible models for the mechanical and magnetic boundary conditions are studied.
