Estimation of stresses and displacements of a rectangular plate after shear buckling using approximate expression by Timoshenko

Nihon Kikai Gakkai ronbunshu, 2020
In the initial design stage of vehicle development, it is important to estimate the strength of the structure against various loads. It is known that buckling occurs in thin-shell structures before yielding as the load increases, and that the structures ...

Geometrically nonlinear theory of thin-walled composite box beams using shear-deformable beam theory [PDF]

, 2009
A general geometrically nonlinear model for thin-walled composite space beams with arbitrary lay-ups under various types of loadings is presented. This model is based on the first-order shear deformable beam theory, and accounts for all the structural ...

Extraction of Inherent Polarization Modes from an m‐Order Vector Vortex Beam

Advanced Photonics Research, 2022
Superposition of two independent orthogonally polarized beams is a conventional principle of creating a new light beam. Herein, it is intended to achieve the inverse process, namely, extracting inherent polarization modes from a single light beam ...

Behaviour of prestressed box beam strengthened with CFRP under effect of strand snapping

Građevinar, 2020
The study aims to evaluate behaviour of a prestressed box beam strengthened with the Carbon Fibre Reinforced Polymer (CFRP) under the snapping of prestressed strands. Three external prestressed box beams are tested until failure.
