An evaluation of finite element models of stiffened plates subjected to impulsive loading
… very common structures, a cantilever beam and a stiffened plate, subjected to impulsive loading. For the cantilever beam case, the finite element models are one, two or three dimensional models. Various results from the finite element analyses are compared including with analytical solution and a …

The elastic rigidities of ribbed plates
… flexural and twisting rigidities of orthotropic plates. Asymmetrically stiffened plates are examples of technically orthotropic plates and are found in civil engineering structures such as bridges and ribbed floor slabs. The formulae for the rigidities as found in the literature are reviewed. The …

Tranverse Deck Reinforcement for Use in Tide Mill Bridge
… that the HCB bridge was behaving more like a stiffened plate at the middle section of the bridge, indicating that the flexibility of the girders needed to be considered.

Aeroelastic Analysis of Rotor Blades Using Three Dimensional Flexible Multibody Dynamic Analysis
… has been developed specifically for folded plate and shell structures. The plate element does not suffer from either shear or aspect-ratio locking under transverse and membrane bending, respectively. A stiffened plate element has been developed that combines a shear deformable plate with a …

Local Continuum Sensitivity Method for Shape Design Derivatives Using Spatial Gradient Reconstruction
… and nonlinear static bending of rectangular plates, linear and nonlinear static bending of a beam-stiffened plate, and two-dimensional potential flow. The analyses are conducted using general purpose codes. For each example the design derivatives are validated with either analytic or finite …

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 …

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 …

Optimal Design and Analysis of Bio-inspired, Curvilinearly Stiffened Composite Flexible Wings
… element approach is developed in designing stiffened composite panels with arbitrarily shaped stiffeners for buckling and vibration analyses. The developed approach allows the finite element nodes for the stiffeners and panels not to coincide at the panel-stiffeners interfaces. The …

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 …
