Abstract

In this paper, at the first time, free vibration and buckling analysis of the cylindrical sandwich panels whit flexible cores and Magneto-Rheological Fluid Layers for simply supported boundary conditions are studied based on an improved higher order sandwich panel theory. In order to validate the results, the obtained results were compared with those obtained using finite element ABAQUS software. In this investigation, the effects of MAGNETIC FIELD, geometrical parameters such as the length to radius ratio, the core thickness to panel thickness ratio, MR layer thickness to panel thickness ratio and Fiber angle on the NATURAL FREQUENCY, buckling Load and LOSS FACTORs of sandwich structure were investigated. The results suggest that the natural frequencies, CRITICAL BUCKLING LOADs (eigen values) and the modal transverse displacements (eigen vectors) of the cylindrical sandwich panels whit flexible cores and Magneto-Rheological Fluid Layers in the face sheets are strongly influenced by the intensity of the applied MAGNETIC FIELD.
