Item Dynamic Analysis of the Non-Linear Behavior of a Composite Sandwich Beam with a Magnetorheological Elastomer Core(2016) Chikh, N.; Nour, Abdelkader; Aguib, Salah; Tawfiq, I.This work deals with the active control of the vibrations of mechanical structures incorporating magnetorheological elastomer. The damping coefficient and shear modulus of the elastomer increase when exposed to a magnetic field. Compared with the vibration control where the elastomer is permanently exposed to a magnetic field, the control of this process through time reduces vibrations more effectively. The experimental study for the vibrations of a sandwich beam filled with an elastomer is conducted, followed by a numerical study using the Abaqus code. The vibration damping is found to be dependent on the loading rate of micro-size ferromagnetic particles in the elastomerItem Numerical simulation of the nonlinear static behavior of composite sandwich beams with a magnetorheological elastomer core(Elsevier, 2016) Aguib, Salah; Nour, Abdelkader; Benkoussas, B.; Tawfiq, I.; Djedid, T.; Chikh, N.Item Forced transverse vibration of composite sandwich beam with magnetorheological elastomer core(Springer, 2016) Aguib, Salah; Nour, Abdelkader; Djedid, Toufik; Bossis, Georges; Chikh, Noureddine
