Dynamic response of foam-filled conical tubes under impact loading

Ahmad, Zaini & Thambiratnam, David P. (2008) Dynamic response of foam-filled conical tubes under impact loading. In 4th International Conference on Advances in Mechanical Engineering and Mechanics, 16-18 December 2008, Sousse, Tunisia.


This paper treats the dynamic crush response and energy absorption of aluminum foam-filled conical tubes subjected to impact loading. Nonlinear dynamic computer simulation techniques are used together with validated computer models. The main goal of the study is to generate fundamental information on the dynamic response and energy absorption of foam-filled conical tubes with respect to the variations in geometry, material and loading parameters. The research information is quantified in terms of important impact response parameters such as mean crush load, total energy absorbed and crush force efficiency that can be used in practical applications. Results indicate that foam-filled conical tubes are efficient impact energy absorbers under both axial and oblique loading conditions. The research finding can be used to develop guidance for the design of these devices for impact applications.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
