Title : An investigation of material effects on the dynamic behavior of composite materials incorporated with MR-fluid using an N-layer model
Abstract: Laminated composite beams incorporated with magneto-rheological fluids (MRlaminated-beam) are being widely used in many engineering applications. The effect of base materials on dynamic response of MR-laminated-beams were investigated using an N-layermodel based on layerwise-theory-(NLWT). Different composite materials including E-glass, fiber-carbon and Kevlar have been considered to determine the vibration response of the structures. Accuracy of NLWT has been verified by comparing the results with first-ordershear-deformation-theory-(FSDT) and experimental-tests. By applying magnetic fields, natural-frequencies of MR-laminated-beams have been increased. It is concluded that, applying 1400-Gauss magnetic fields to low-cost materials like E-glass provides the same naturalfrequency as fiber-carbon without magnetic fields.
