Structural Assesment of Corroded Beams
ECS Transactions, 2006 This paper shows how the corrosion and mechanical actions can be taken into account in a simple model for the assessment of structural elements. This work is framed in the Project Benchmark des Poutres de La Rance in which several partners have participated.

Coupled tension-torsion vibration of repetitive beam-like structures [PDF]
, 2006 Equivalent continuum stiffness properties, derived from the eigenanalysis of a single cell of a planar beam-like repetitive structure, have previously been employed within well-known dynamic theories, such as Euler–Bernoulli and Timoshenko for flexural ...

Longitudinal Fracture Analysis of Continuously Inhomogeneous Beams Undergoing General Planar Motion [PDF]
Journal of Applied and Computational MechanicsThis paper is devoted to longitudinal fracture in continuously inhomogeneous non-linear elastic beam structures which undergo general planar motion. First, a unified approach for treatment of the problem is presented assuming law of planar motion in ...

Helical structure of the waves propagating in a spinning Timoshenko beam [PDF]
, 2005 The aim of the paper is to study the cause of a frequency-splitting phenomenon that occurs in a spinning Timoshenko beam. The associated changes in the structure of the progressive waves are investigated to shed light on the relationship between the wave

Steady-state vibrations of a beam structure under moving horizontal force-analytical approach [PDF]
Archives of Civil EngineeringThe following paper presents a dynamic analysis of a railway superstructure subjected to horizontal moving loads. The superstructure including the substructure was modelled with two infinitely long beams connected by an elastic layer. The structure rests

A nonlinear beam model of photomotile structures [PDF]
Proceedings of the National Academy of Sciences, 2020 Significance Actuation and propulsion are significant challenges in soft robotics. Supply of power typically requires a cumbersome tether or heavy onboard power source. Further, one typically needs to reset the system. Using theory and numerical simulations, we show, in this work, that this challenge can be overcome by the use of ...

Advanced beam theories for the analysis of beam structures [PDF]
, 2021 Η παρούσα διδακτορική διατριβή αποτελεί συμβολή στην ανάπτυξη εξελιγμένων θεωριών δοκού για την ανάλυση ραβδωτών φορέων. Οι εξελιγμένες θεωρίες δοκού που αναπτύχθηκαν λαμβάνουν υπόψη φαινόμενα γενικευμένης στρέβλωσης (διατμητική υστέρηση λόγω κάμψης και στρέψης), διαστρέβλωσης (παραμόρφωση διατομής – distortion), ενώ πραγματοποιείται και γεωμετρικά μη ...
