Numerical Investigation of the Modal Analysis for Multi Layers Composite Plate

A three-dimensional parametric model was employed to recreate the free response laminated composite plate constructed from different materials. Simulation of the modal analysis is powerful when extreme localized modes are of problem, and it demands dependable material structural models along with correct modelling methodologies. A classical theory-based finite element approach was created to explore the effect of material attributes upon the natural vibration behavior for thin laminated plates. The approach was validated using three-dimensional deformation findings and also achieved based on the theory's results with those derived from commercial programs, including Solidworks. The results obtained from software are in good agreement for some cases and significantly differ for free vibration and is highly dependent on the material properties and boundary conditions. For simply supported boundary condition, the results showed that the maximum fundamentals frequency was 1808.5Hz Hz for the carbon/epoxy material. An established computational technique, depending on finite element method, has been proposed for the computation of free vibration in reinforcement laminated composite components. a good result for estimate the natural frequency and mode shape.
