Modeling and finite element simulation of the magneto-mechanical behavior of ferrogels

Review on the advancements of magnetic gels: towards multifunctional magnetic liposome-hydrogel composites for biomedical applications

“…Concerning the requirement of understanding the behaviour of these materials to tailor with the desired properties, various theoretical studies have been carried out, including the use of molecular dynamics [197][198][199][200][201][202][203][204][205][206]. For instance, Lopez-Lopez et al [207] evaluated the effect of the magnetic field-induced nanoparticle rearrangement on the shear elasticity of isotropic magnetic gels.…”

Determination of representative volume element size for a magnetorheological elastomer

“…We now define the stiffness ratio β c , as a ratio between inclusions and matrix stiffnesses, see Eq. (11). β c ranges (5, 25, 100) introduce a change in heterogeneity.…”

“…It was shown that the elastic modulus can be controlled by applying a uniform magnetic field to the samples at the gelformation stage. A macroscopic model has been proposed by Attaran et al [11] to capture the mechanical deformation of ferrogels. The authors have simplified a previously developed continuum model for this reduced form, and it was reported that this reduced model shows good agreement with the experimental results.…”

Stimuli-responsive twist actuators made from soft elastic composite materials -- linking mesoscopic and macroscopic descriptions

“…Upon magnetization by a homogeneous external magnetic field, such materials generally show an overall deformation of the magnetostrictive type. So far, mainly linear types of induced distortion have been considered in an external magnetic field, either homogeneous or inhomogeneous, implying extensions or contractions along straight global axes of deformation 3,[16][17][18][19][20][21][22][23][24][25] .…”
