Vibration Analysis of Laminated Composite Plates with Holes
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 7
Abstract
Fiber reinforced composite materials are widely used in variety of engineering applications due to its superior properties than the conventional materials. In this investigation free vibration analysis of four layered angle-ply symmetric laminated plates with various lamination angles (±0o to ±90o )s of laminas with different hole locations were presented. The analyzed laminated plates have been made from composite materials: the reinforcement fibers were Graphite and the matrix material is Epoxy. Composite structures may sometimes provided with holes for the purpose of assembling the components, for passing the cables, for inspection and maintenance etc. The ANSYS13.0 software was used for modeling and analysis of the laminated plates under clamped boundary conditions. The eight noded shell99 was used throughout the analysis. Length to height ratio considered is 40 and 200. The ratio of hole area to the plate area is maintained constant throughout the analysis as 0.05. From the analysis it is inferred that the fundamental frequency of laminated composite plates decreases with increase in L/h ratio.
