Optimally stiffened thin shell structures in 3D printing.
… which connects frame to skin at nodes; • The stiffened plate theory takes stiffeners and surface as a coupled system by adding stiffness contribution of stiffener elements to corresponding plate elements which yields more accurate solution; • The strength or ability to resist bending can be …

Parametric study of stiffened steel containment shell structures
… behavior of meridionally and circumferentially stiffened steel cylindrical and conical shell frustum subjected to different load cases. This situation arises in different steel shell applications such as storage vessels (liquid, solid and gas) and in certain configurations of industrial process …

Passive Damping in Stiffened Structures Using Viscoelastic Polymers
… to incorporate viscoelastic material in a thick stiffened panel with plate-strip stiffeners, to enhance the damping characteristics of the structure. First, we investigated complex damped modes in beams in the presence of a viscoelastic layer sandwiched between two elastic layers. The problem was …

Multidisciplinary Optimization and Damage Tolerance of Stiffened Structures
… spars and ribs greatly influences the design of stiffened panels. During the local panel optimization, the stress information is taken from the global model as a displacement boundary condition on the panel edges using the so-called "Global-Local Approach". The aircraft design is characterized by …

Layerwise theory for discretely stiffened laminated cylindrical shells
… Shell Theory is used to model discretely stiffened laminated composite cylindrical shells for stress, vibration, pre-buckling and post-buckling analysis. The layerwise theory reduces a three-dimensional problem to a two-dimensional problem by expanding the three-dimensional displacement …

Optimal design of geodesically stiffened composite cylindrical shells
… to obtain minimum-weight designs of composite stiffened structures. Ply thicknesses, ply orientations, and stiffener heights can be used as design variables. Buckling, displacement, and material failure constraints can be imposed on the design. The system is used to conduct a design study of …

Control of Radiated Noise from Fluid-Loaded Stiffened Structures
Periodically stiffened structures are widely used in many engineering applications, including aeronautics, marine, and rail systems. In these structures, so called Bloch-Floquet (BF) waves are generated due to the interaction between flexural waves in the host structure and flexural/torsional waves …

Three-Dimensional Finite Element Analysis of Stiffened Tee-Hangers.
All framed steel structures require moment-resistant connections to join the various members. These connections form a more rigid structure using less steel by distributing the moments throughout the structure. However, the moment-resistant connection geometry combines with the support conditions …

Thermal Analysis and Response of Grid-Stiffened Composite Panels
… and thermal buckling loads of rectangular grid-stiffened composite panels is presented. Two edge conditions are considered for the panel, one in which all panel edges are free to deform, and another when all the edges are restrained. In the first case panel deformations due to a uniformly …

Combined structural and manufacturing optimization of stiffened composite panels
… into the design optimization of a blade-stiffened composite panel. For the manufacturing analysis, a one-dimensional resin film infusion model is developed to compute the infiltration time of the resin into a fabric preform of the panel. Results are presented showing the effects of …

Optimum crashworthiness design of grid-stiffened composite fuselage structures
… into the preliminary design of grid-stiffened composite fuselage structures. The crash analysis of a fuselage structure was simplified through the development of a global-local procedure, which reduces the computational requirements of a crash simulation while facilitating the …
