Energy Absorption Characteristics of Coiled Expanded Metal Tubes Under Axial Compression

Abstract

This paper presents an experimental investigation on the axial crushing of coiled expanded metal tubes subjected to quasi-static compressive loading. The investigation aims at comparing the energy absorption characteristics between tubes fabricated with coiled expanded metal meshes and solid plates. Then, a series of quasistatic axial crushing tests were performed to obtain the structural performance on coiled tubes, and then compare these with round and square solid tubes. Coiled tubes were fabricated using circular and square geometries, as well as various cell orientations. The results showed that cell orientation enhance the energy absorption response of the coiled tubes. Regarding these responses in comparison to those of solid tubes, the results showed that for coiled and solid tubes with the same weight, the energy absorption capacity of the former is much lesser than the latter.

Effect of Relative Density on Compressive Load Response of Crumpled Aluminium Foil Mesh

“…A review of expanded metal patents up to 2009 was published by Smith showing a wide range of applications [23]. Subsequent work has been performed to understand the compressive and impact behavior of expanded metal tubes [24,25] and nested tubes placed concentrically to form a 3D structure. Expanded metal tubes show improved energy absorbance [26,27] including with additional foams added [28].…”

Experimental and numerical investigation of lattice core sandwich beams under low-velocity bending impact

“…This is because damping of the force must be gradual in these systems. By observing the failure mode of the expanded metal sheets and their deformation configuration, we conclude that the deformation mechanism is layered [17–19].…”
