... and results include: (i) exact boundary condition enforcement through Jacobi weight function for FSDT, (ii) formulation of quadrilateral plates with curvilinear stiffeners, and (iii) use of higher order Gauss quadrature scheme for required integral evaluations to obtain higher modes. It is demonstrated...

... shells curvilinear stiffeners Stiffened shallow shell structures are used extensively for the construction of a variety of engineering structures, such as road tankers, offshore structures, aircraft fuselages, submarines, and so on. It is observed that stiffeners can improve the static...
