“…Shi and co-workers [34] analysed a static response and buckling loads of plates stiffened with arbitrary placed curved stiffeners. Bedair [35] committed the paper that was devoted to the problem of the design of stiffened box girders, in case of web shear buckling. Panda and Barik [36] developed a 4-noded stiffened plate FE, based on an isoparametric approach with the shearlocking problem solved.…”

“…In the last numerical example, the buckling of a box section is analysed. A literature survey and description of references where the selected design problems of box sections are addressed could be found in the paper by Bedair [35]. To the best author's knowledge, there are no reference examples or design expressions for buckling of box sections in the scientific literature.…”

The present research investigates the theory and numerical analysis of shells stiffened with beams in the framework based on the geometrically exact theories of shells and beams. Shell’s and beam’s kinematics are described by the Cosserat surface and the Cosserat rod, respectively, which are consistent including deformation and strain measures. A FEM approximation of the virtual work principle leads to the conforming shell and beam FE with 6 DoFs (including the drilling rotation for shells) in each node. Examples of static and stability linear analyses are included. Novel design formulas for the stability of stiffened shells are included.

“…Characterization related to stability behavior of a composite structure with thin walls, ultralight and high rigidity, such as open box type [5,6] or closed box type [7,8], with reinforcing elements, requests a numerical theoretical analysis [9,10], finite element method analysis [11,12], or experimental analysis [13,14]. Such structures behavior strongly depends on wall thickness, ribs configuration, the fibers orientation angle inside sandwich or type of applied load.…”

Composite materials are mostly used in applications where stiffness-to-weight or strength-to-weight ratios are critical. For example, there can be produced a large number of acceptable designs that support a specific loading condition by varying fibre orientation in each ply, or in a certain number of plies. Due to ease of construction, structural elements, such as box structures, are widely used as a load bearing member in the fields of civil, mechanical and aeronautical engineering. The paper presents an analysis of finite element stability of a thin-walled structure which can be used in civil constructions. The structure is made of FRP composite material. The structure is stiffened with ribs which are made of the same composite, steel and aluminum. The critical buckling pressure was determined for this structure. The advantage of using FRP and sandwich composite, compared to conventional materials as steel or aluminum, consists in high strength to weight ratios, high corrosion resistance, lightweight and excellent fatigue performance. A neural network model was created and used for the prediction of stability behavior of the analyzed elements.
