“…The force-displacement response curves show gradual increase in the force, which is a favorable behavior for an energy absorbing system since in these systems damping of the force must be gradual. By observing the failure mode of the expanded metal tube and its deformation configuration, we conclude that the deformation mechanism is layered (Graciano et al, 2009(Graciano et al, , 2012. Alghamdi (2001) introduced research conducted during the past four decades on energy absorbers subjected to impact loading.…”

“…Two types of collapse were observed under quasi-static loads. A distinct plastic collapse occurred in   0 and led to a global buckling and the failure of the structure in the 90-degree angle (Graciano et al, 2012). …”

“…Latticed energy absorbers can meet all the requirements for efficient energy absorption. Graciano et al (2012) studied the axial collapse of circular tubes made of expanded metal sheets. Their test results showed that the collapse mechanism depended on cell direction, and that the initial peak force depended on the number of cross sectional cells (Graciano et al, 2012).…”

This research was an experimental and numerical investigation of the cylindrical expanded Sheets under impact loading. Two types of absorbers with different cell angles were examined (i.e.  =0 and  =90). The experiments were performed using the drop hammer setup, and the numerical simulations were conducted by ABAQUS. In this study, the type of collapse, force-displacement diagrams, the crushing length, and the absorbed energy were investigated. The experimental and numerical results were compared, and it was observed that they were in good agreement. Results showed that the absorbers with the cell angle of α=0 had a symmetric collapse and a high energy absorption capacity. Also, various heights of fall were considered for the impact mass to examine the type of collapse in the models. The crushing amounts of the models were also compared in different heights. Multi-walled expanded metal tubes were studied, and the effect of being multi-walled in collapse was examined.Keywords Expanded metal energy absorbers; energy absorption capacity; dynamic axial loading; effect of impact force; finite element.Experimental and numerical investigation of lattice-walled cylindrical shell under low axial impact velocities Nomenclature A the cross section and yield stress at Eq.7

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.

“…These two sheets are hurricane conditions due to windborne debris impact from high-speed winds, [6] investigated a roofi ng system made of SEM panels, the results showed that the roofi ng system was able to resist penetration by heavy objects through the winds. A series of experimental and numerical studies have been conducted [7][8][9] on the collapse of tubes made of SEM meshes subjected to axial compression. The results showed that the collapse mechanism depends on the orientation of the expanded metal cells.…”
