Article Citation - WoS: 47Citation - Scopus: 62Transverse and Longitudinal Crushing of Aluminum-Foam Filled Tubes(Elsevier Ltd., 2002) Hall, Ian W.; Güden, Mustafa; Claar, Terry DennisAl-foam filled and empty tubes of aluminum, brass and titanium were compression tested laterally. The specific energy absorption in filled tubes increased greatly in terms of percentages, and was greatest in aluminum tubes. In transversely tested tubes the foam deformed laterally showing a capability of spreading the deformation.Article Citation - WoS: 29Citation - Scopus: 29Effect of Adhesive on the Strengthening of Aluminum Foam-Filled Circular Tubes(Springer Verlag, 2004) Toksoy, Ahmet Kaan; Tanoğlu, Metin; Güden, Mustafa; Hall, Ian W.Studies of the crushing behavior of closed-cell, aluminum foam-filled aluminum and steel tubes have shown an interaction effect between tubewall and foam filler [1, 2, 3]. The crushing loads of foam-filled tubes are, therefore, found to be higher than the sum of the crushing loads of foam (alone) and tube (alone) mainly due to this effect. Santosa et al. [1], based on FEM results, proposed the following equation for the average crushing load of foam-filled square tubes of length b,Article Citation - WoS: 194Citation - Scopus: 227Dynamics of Metal Foam Deformation During Taylor Cylinder–hopkinson Bar Impact Experiment(Elsevier Ltd., 2003) Lopatnikov, Sergey L.; Gama, Bazle A.; Haque, Jahirul; Krauthauser, Carl; Gillespie, John W.; Güden, Mustafa; Hall, Ian W.Analytical solutions for dynamic deformation of foam materials during the Taylor cylinder–Hopkinson bar impact experiment were obtained. It was shown that shock wave of foam collapse appears during the fast impact. The results of this experiment can be used in estimating the average material properties of the foam under dynamic loading conditions. Results show that the un-deformed and change in length of foam specimens are in good agreement between theory and experiment, as well as numerical analysis.Article Citation - WoS: 124Citation - Scopus: 136Crushing of Aluminum Closed Cell Foams: Density and Strain Rate Effects(Elsevier Ltd., 2000) Hall, Ian W.; Güden, Mustafa; Yu, C.-JThe quasi-static and high strain rate compression behavior of an Al closed cell foam was examined in detail. The compression flow stress of the foam was a function of the relative density but exhibits little or no strain rate density. In addition to the flow stress, the energy absorption was also related to the foam density by a similar power law dependency. Metallographic observations of compressively deformed foam confirmed the general processes of progressive cell wall collapse.
