Static and Modal Analysis of Sandwich Beam Structure with Magnetorheological Honeycomb Core

In this article a sandwich beam structure with honeycomb core filled of MRE (magnetorheological elastomer) with different ratios of Elastomer and iron particles modeled in ANSYS is proposed. The simulation (resonance frequency, total deformation, equivalent stress and equivalent strain) results for structures with PLA (Polylactic acid) and ABS (Acrylonitrile butadiene styrene) honeycomb core were analyzed and compared for two different cases. The results showed that the resonance frequency of the structure decreased as the ratio of iron particles was increased for all the cases, this is due to the increase in stiffness of the structure due to higher ratio of iron particles. Secondly structure with ABS honeycomb core showed lower frequency and higher deformation than the structure with PLA honeycomb core.
