Item Measurements and identification of smart magnetomechanical elastomer composite materials properties in shear mode(Institute of Physics Publishing, 2019) Nedjar, Ali; Aguib, Salah; Djedid, Toufik; Nour, Abdelkader; Meloussi, MounirMagnetorheological elastomer composite materials (MRE) are a new class of intelligent active materials composed of ferromagnetic particles, of micrometric size, dispersed in a silicone elastomer matrix, which exhibit variable stiffness and damping properties which are modifiable under the application of an external magnetic field. Currently, these devices are primarily used in automotive and building applications, but they can easily be adapted to meet the requirements of aerospace applications. The development process and experimental characterization needed to evaluate the active control performance of this material have been made. This is done by characterizing the mechanical properties as a function of the magnetic field, as a function of the excitation frequency and as a function of the different percentage of ferromagnetic particles loading. An example of application of this material in aeronautics is also presentedItem Vibration control of a hydrostatic bearing using magnetorheological elastomer shell bearing(JVE International, 2018) Chikh, Noureddine; Aguib, Salah; Djedid, Toufik; Nour, Abdelkader; Tawfiq, ImadIn rotating machines, random movements or sliding movements of the rotor in its housing can produce undesirable phenomena for some parts. To solve this problem, a new hydrostatic bearing with an intelligent magnetorheological elastomer sell bearing has been designed to control the undesirable vibrations of rigid rotors. The different effects of the influence parameters on the vibratory behavior of the sell bearing are calculated numerically using Abaqus software, and the results found are encouragingItem Analysis of the dynamic behavior of magnetorheological elastomer composite : elaboration and identification of rheological properties(2018) Nedjar, Ali; Aguib, Salah; Djedid, Toufik; Nour, Abdelkader; Settet, Ahmed; Tourab, MohamedItem Forced transverse vibration of composite sandwich beam with magnetorheological elastomer core(Springer, 2016) Aguib, Salah; Nour, Abdelkader; Djedid, Toufik; Bossis, Georges; Chikh, Noureddine
