Effects of particle distribution on mechanical properties of magneto-sensitive elastomers in a homogeneous magnetic field
We propose a theory which describes the mechanical behaviour of magneto-sensitive elastomers (MSEs) under a uniform external magnetic field. We focus on the MSEs with isotropic spatial distribution of magnetic particles. A mechanical model is used in which magnetic particles are arranged on the site...

irk-123456789-1201722017-06-12T03:02:34Z Effects of particle distribution on mechanical properties of magneto-sensitive elastomers in a homogeneous magnetic field Ivaneyko, D. Toshchevikov, V. Saphiannikova, M. Heinrich, G. We propose a theory which describes the mechanical behaviour of magneto-sensitive elastomers (MSEs) under a uniform external magnetic field. We focus on the MSEs with isotropic spatial distribution of magnetic particles. A mechanical model is used in which magnetic particles are arranged on the sites of three regular lattices: simple cubic, body-centered cubic and hexagonal close-packed lattices. By this we extend our previous approach [Ivaneyko~D. et al., Macromolecular Theory and Simulations, 2011, 20, 411] which used only a simple cubic lattice for describing the spatial distribution of the particles. The magneto-induced deformation and the Young's modulus of MSEs are calculated as functions of the strength of the external magnetic field. We show that the magneto-mechanical behaviour of MSEs is very sensitive to the spatial distribution of the magnetic particles. MSEs can demonstrate either uniaxial expansion or contraction along the magnetic field and the Young's modulus can be an increasing or decreasing function of the strength of the magnetic field depending on the spatial distribution of the magnetic particles. Ми пропонуємо теорiю, яка описує механiчну поведiнку магнiтночутливих еластомерiв (МЧЕ) з iзотропним розподiлом частинок в однорiдному магнiтному полi. Використовуються три механiчнi моделi, в яких магнiтнi частинки помiщено у вузлах вiдповiдно трьох перiодичних ґраток: простої кубiчної, об’ємо-центрованої кубiчної та щiльно впакованої гексаґональної. Цим ми розвиваємо наш попереднiй пiдхiд [Ivaneyko D. et al., Macromolecular Theory and Simulations, 2011, 20, 411], в якому ми використали лише просту кубiчну ґратку для опису просторового розподiлу частинок. Деформацiя, яка виникає пiд впливом магнiтного поля, та модуль Юнга в МЧЕ розрахованi для рiзних напруженостей магнiтного поля. Ми показали, що магнiтномеханiчна поведiнка МЧЕ сильно залежить вiд просторового розмiщення магнiтних частинок. МЧЕ демонструє одновiсне видовження або стиск вздовж магнiтного поля, а модуль Юнга зростає або спадає при збiльшеннi напруженостi магнiтного поля залежно вiд просторового розподiлу магнiтних частинок. 2012 Article Effects of particle distribution on mechanical properties of magneto-sensitive elastomers in a homogeneous magnetic field / D.
