Vibration Analysis of Laminated Composite Plate using Finite Element Analysis

This work is concerned with vibration (Modal) analysis of a laminated composite plate structure with different Angle orientation of ply. The finite Element method has been used computational by means of ANSYS 14.5. a main reason for adopting ANSYS 14.5 is that there is no such analytical model has been develop for Laminate composite plate structure in presence of singularities i.e. Cutout. Moreover parametric analysis has also been carried out for detailed convergence study plate vibration in presence of cutout. Following analysis have been carried out for different boundary condition i.e. CFFF and SSSS to allocate optimum location of cutout for optimum natural frequency in order to make laminate composite structure statically and dynamically balanced The obtained FEM results are validated with experimental and analytical result of available literature and it result shows good agreement.
