Probabilistic Analysis of a Thin-walled Beam with a Crack
… response. The damaged wing is modeled by a thin-walled beam with a longitudinal crack the response of which can be obtained analytically. As uncertainties are present in the location and size of the crack as well as in the applied loads, their effects are incorporated into the framework …

Modeling and response analysis of thin-walled beam structures constructed of advanced composite materials
Thin-walled beam structures are adopted as structural members in various fields of modem technology including aeronautical/aerospacial, naval, mechanical and civil ones. With the advent of advanced composite material systems, there is a vital need to reformulate the classical theory of thin-walled …

Finite element formulation of a thin-walled beam with improved response to warping restraint
Linear elastic theory of torsion and flexure of thin-walled beams as developed by Vlasov and Timoshenko respectively are well known and commonly used in everyday engineering practice. However there are noticeable differences between calculations and experimental results. The difference is partly …

Vibration and Aeroelasticity of Advanced Aircraft Wings Modeled as Thin-Walled Beams--Dynamics, Stability and Control
Based on a refined analytical anisotropic thin-walled beam model, aeroelastic instability, dynamic aeroelastic response, active/passive aeroelastic control of advanced aircraft wings modeled as thin-walled beams are systematically addressed. The refined thin-walled beam model is based on an …

Control of Dynamic Response of Thin-Walled Composite Beams Using Structural Tailoring and Piezoelectric Actuation
… to control the dynamic response of cantilever beams subjected to external excitations is addressed. The cantilevered structure is modeled as a thin-walled beam of arbitrary cross-section and incorporates a number of non-classical effects such as transverse shear, warping restraint, anisotropy …

The theory of anisotropic thin- and thick-walled closed cross-section beams with coupled elastic deformations
… and accurate anisotropic closed-section beam theory has been developed for both thin- and thick-walled composite beams. In this theory transverse shear effects, both of the cross-section and of the beam walls, are taken into account. Torsional warping, both free and constrained as well as …

COMPLEX FREQUENCY ANALYSIS OF DAMPED THIN-WALLED BEAMS WITH OPEN CROSS SECTIONS (COUPLED, VIBRATION)
<p>The dynamic equilibrium equations for thin-walled beams of open cross section are derived with reference to an arbitrary system of coordinates. Exact stress resultant-displacement relation of the bending theory of cylindrical shells has been used and therefore the shell curvature, secondary …

Elastic Lateral Torsional Buckling of Beams Strengthened with Cover Plates while under Loading
… method for strengthening existing steel I-beams is to weld either one or two cover plates to the flange(s). In many cases, it is not feasible to completely unload the beam before carrying out the strengthening procedure. In these conditions, operators resort to strengthen beams while under …
