Discussion: EXPERIMENTAL AND NUMERICAL MODAL ANALYSIS OF COMPOSITE LAMINATED SHELLS WITH CUT-OUT - Copy

In the construction of the ship hull, boats and other complex marine structures with lightweight requirement laminated composite shells (both shallow and deep) with their unique material properties as well as advantageous structural forms are preferably provided as primary structural components. The cut-outs in shells are necessary for heat dissipation, undertaking maintenance, fitting auxiliary equipment, access ports for mechanical and electrical systems, damage inspection of the structures etc. Presence of cut-outs affects the dynamic characteristics of the shells altering the resonant frequency. Henceforth, the study of dynamic behaviour of laminated shells with cut-outs becomes necessary to avoid
