Laminated Composites are increasingly being used currently in civil, aerospace, marine and other related weight-sensitive engineering relevance‘s requiring high stiffness-toweight and strength-to-weight ratios. Some of the structural components of, missile, aircrafts and ship structures can be idealized as composite plates and shell. 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 15.0. a main reason for adopting ANSYS 15.0 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
Variable cut out size
Laminate composite Plate with different cut out types i.e. Square and Circle.
laminate composite Plate with different Ply orientation
laminate composite Plate with different Ply orientation in presence of cut out
The obtained FEM results are validated with experimental and analytical result of
available literature and it result shows good agreement.
