Comparison of Different Local Unrefined Beam Theories for Bending and Nano Beams Buckling Analysis

Autor: hamza madjid berrabah, Adda Bedia El Abbas, Tounsi Abdelouahed

Publikováno v: Journal of Materials and Engineering Structures, Vol 3, Iss 1, Pp 2-13 (2016)

In this study, non unified local shear deformation theory is proposed to consider the bending and buckling of nano beams. This theory is based on the assumption that the cross-sectional and planar displacements consist of bending and shear components

Non-linear finite element analyses have intrinsic model and user factors that influence the results of the analyses. However, non-linear finite element analysis can provide a tool to assess safety using realistic descriptions of material behaviour wi

The gap between theory, practice and regulations in design criteria for iron and steel structures in 19th century France : the example of train sheds

Autor: Franz, Hannah, Rinke, Mario, Lepretre, Emilie, Dieng, Lamine

Publikováno v: Proceedings of the Ninth Conference of the Construction History Society, 1-3 April, 2022, Cambridge, UK

In the 19th century, the concept for designing metallic structures was to compare the stresses resulting from the loads with a working stress, a fraction of the ultimate strength of the material. The choice of the working stress depended mainly on th

Étude expérimentale et théorique de la stabilité et la rigidité des membranes lipidiques dans différents conditions

Autor: Eid, Jad

In this work, we quantified the rigidity of blanc EggPC liposomes and liposomes of the same type encapsulating quercetin. For this purpose, we measured the Young modulus from the force curves in the Force Spectroscopy mode of AFM Atomic Force Microsc

Development of a model of stability for steel hollow tubular section beam-columns sensitive to second order effects

Autor: Mercier, C.

Publikováno v: Structures. Université de Lorraine, 2019. Français. ⟨NNT : 2019LORR0113⟩

This thesis is part of an effort to improve knowledge of the instabilities of beam-columns sensitive to second-order effects. The works deal with the means to take into account the initial imperfections in the structural analysis and to adapt the cur
