Experimental and Numerical Investigation of Crushing of Brass Cylindrical Tubes

Authors

Abstract

Thin-walled structures have been extensively usedas energy absorbers in automobile and aerospace industries.This paper treats the collapse behaviour and energy absorption response of brass cylindrical tubes subjected to axial loading, using experiment and non-linear finite element models. In experimental approach, brass cylindrical samples were made by the process of extrusion. These samples are compressed between two rigid platens under quasi-static loading conditions and the collapse mechanism, the variations of crushing load and absorbed energy are determined. A numerical model is presented based on finite element analysis to simulate the collapse process considering the non-linear responses due to material behaviour, contact and large deformation. The comparison of numerical and experimental results showed that the present model provides an appropriate procedure to determine the collapse mechanism, crushing load and the amount of energy absorption. Numerical simulation techniques validated are used to carry out a parametric study of brass cylindrical tubes. In the following, influence of important parameters such as geometry imperfection (wall thickness gradient and wave formation), boundary condition, semi-apical angle, multi-cell columns reinforace and velocity impact was investigated. The results of this paper highlight the advantages of using brasscylindrical tubes as energy absorber.
