Conference Object Axial Compression of Aluminum Closed-Cell Foam Filled and Empty Aluminum Tubes(Uludağ Üniversitesi, 2002) Toksoy, Ahmet Kaan; Güden, Mustafa; Hall, Ian W.Aluminum closed-cell foam filled aluminum tubes with a polyester bonding layer between foam core and tube wall have been compression tested in ord er to detemiine specific energy absorption for the crash box applications. Aluminum foam, empty and foam filled tubes without bonding layer were also tested for comparison purposes, Preliminary results have shown that interaction effect has been found in foam filled tubes with polyester layer. In order to identify deforiDation mechanisms involving with tube deforination, deformed empty and foam filled tubes crosssections were microscopically analyzed and operative defoimationmechanisms were determined.Article Citation - WoS: 19Citation - Scopus: 19Experimental Investigation of Interaction Effects in Foam-Filled Thin-Walled Aluminum Tubes(Springer Verlag, 2006) Güden, Mustafa; Toksoy, Ahmet Kaan; Kavi, HalitThe interaction coefficients of polystyrene foam filling of thin-walled aluminum cylindrical tubes were investigated experimentally through compression testing of partially foam-filled tubes with and without adhesive. The experimental load-displacement curves and observation of the crushed sections of filled tubes have shown that partial foam filling reduced the fold length and hence increased the average crushing loads of tubes, proving the interaction effect between tube wall and filler. The interaction coefficients for the partial foam filling were further calculated to be in the level and/or higher than that of the foam plateau load of transverse direction.
