The presence of cutouts at different positions of laminated shell component in marine and aeronautical structures 
facilitate heat dissipation, undertaking maintenance, fitting auxiliary equipment, access ports for mechanical and 
electrical systems, damage inspection and also influences the dynamic behaviour of the structures. The aim of the 
present study is to establish a comprehensive perspective of dynamic behavior of laminated deep shells (length to radius 
of curvature ratio less than one) with cut-out by experiments and numerical simulation. The glass epoxy laminated 
composite shell has been prepared in the laboratory by resin infusion. The experimental free vibration analysis is carried 
out on laminated shells with and without cut-out. The mass matrix is developed by considering rotary inertia in a lumped 
mass model in the numerical modeling. The results obtained from numerical and experimental studies are compared for 
verification and the consistency between mode shapes is established by applying modal assurance criteria.
