Abstract: This paper is concerned with the galloping of iced conductors modeled as a two-degrees-of-freedom system. It is assumed that a realistic cross-section of a conductor has eccentricity; that is, ...

Abstract: Although the galloping of an iced electrical conductor has been considered by many researchers, no special attention has been given to the galloping’s sensitivity to alternations in the system’s ...

Abstract: A parallel computational algorithm that models three-dimensional elastic wave scattering in an infinite pipe is introduced. The algorithm combines two procedures: a Wave Function Expansion (WFE) ...

Abstract: A novel numerical procedure is presented in this paper to study wave scattering problem by circumferential cracks in steel pipes. The study is motivated by the need to develop a quantitative ...

Abstract: A three‐degree‐of‐freedom model is developed to comprehensively describe and predict different galloping behavior observed on a single iced, electrical transmission line. Interactions are accommodated between a line's ...

Abstract: Internal nonresonant and resonant galloping of an iced electrical transmission line is studied by employing a three‐degree‐of‐freedom (3DOF) model formulated in part

Abstract: A comprehensive analysis is presented for the galloping of an oscillator that may vibrate both transversely and torsionally. Explicit solutions are given for the conditions needed to initiate galloping and also for the ...

Abstract: A semi-analytical finite element (SAFE) formulation is proposed to study the wave propagation characteristics of thin-walled members with an infinite length in the longitudinal (axial) direction. ...
