The Lateral Distortional Buckling of I-Plate Girders [PDF]

Journal of Engineering Research, 2019
Cet article présente une étude numérique pour le flambage par distorsion latérale des poutres en I (LDBIPG) en utilisant le logiciel ABAQUS (version 6.13). Des modèles 3D à éléments finis (FE) pour des IPG simplement supportés soumis à deux cas de chargement sont construits.

Numerical Analysis of Circular Pre-notched U-Channel Section Distortions in Cold Roll-Forming Process [PDF]

International Journal of Advanced Design and Manufacturing Technology, 2017
Cold roll forming is a process in which a metal sheet gets a desired section form by passing through a series of rotating rollers. Predicting the amount of the distortion in pre-notched cold formed sections still remains challenging in cold roll forming ...

RESEARCH OF DISTORTIONAL BUCKLING OF STRINGER

Авіаційно-космічна техніка та технологія, 2018
Local buckling of elements supporting the compressed power panels of aircraft structures, stringer, is considered. It has been shown that the identification of critical stresses of the local stability of the stringer and the critical stresses of its weakest wall can lead to significantly overestimated results. The use of this approach omits the form of
