Comparative Analysis of Buckling Load of Circular and Corrugated Tubes by Utilizing Key Performance Indicators

Abstract

The performance of buckling load of tubular structures under quasi-static axial loading is quite appreciable, numerous tubes of various cross-section have been extensively investigated and corrugated sections have been designed to further improve the performance. In this paper, a carefully designed set of key performance indicators (KPIs) is utilized to assess and compare the buckling load of circular and corrugated tubes. A series of diagrams related to KPIs with various parameters of tubes are presented to demonstrate the influence of sectional configuration on the performance of tubes as well as the effect of the material on the potential of the same. The work is inestimable to engineering designs and applications, and further studies on the buckling load of other configurations.

Axial Crushing Behaviors of Thin-Walled Corrugated and Circular Tubes - A Comparative Study

“…Corrugated structures show exceedingly anisotropic behavior and high stiffness transverse to the corrugation direction [15]. The influence of the degree of amplitude and wavelength of corrugated tubes on energy absorption (EA) and peak crushing force(PCF) was reported by Sharad Rawat et al [16].The previous study reveals that buckling load can be easily enhanced by changing cross-section from circular to corrugated [17].The avail of using corrugated cross section is that with a slight increase in weight there is a significant rise in peak force and energy absorption over comparable tubular sections. In the present work, the crushing behavior and the energy absorption of corrugated and circular tubes under quasi-static axial loading were investigated numerically.…”

Buckling Analysis of Innovative Corrugated Column by using Response Surface Methodology

“…1 shows the hollow corrugated column with sinusoidal pattern used in the present paper. Since it is found that corrugation makes the structure more strength along the length of the column [7] as compared to conventional circular hollow columns. As buckling is the most important phenomenon as a result of axial-compression forces.…”

Finite element Analysis of Honeycomb filled Metallic Tubes Subjected to Axial Loading

“…It was found that by increasing the number of corners of polygon its energy absorbing capacity also increases but to a certain extent [6]. The previous study shows that the buckling load was of the thin-walled metallic tubes were increased when the cross sections were combined [7] and corrugation was introduced [8]. In addition to these, metallic honeycomb is also used widely as an extension for its high energy dissipating mechanism and an excellent strength to mass ratio.…”
