Crushing Behaviour of Empty Steel Tubes under Oblique Loading

Abstract:

This paper presents numerically the empty tube response subjected to oblique loading. According to literature survey, there have large number of works discuss on the crushing performance when subjected to axial loading. However, lack of work available on the crushing behaviour under oblique loading. Therefore, this work presents the numerical studies on the crushing behavior of empty tube subjected to oblique loading. ANSYS Finite element program was used to model and solve the problem. The developed model was firstly validated with the previous result and it is found that the results obtained were acceptable. There were two important parameters were used such as tube geometry and oblique loading. According to the present results, when oblique angles were increased, the crushing performance decreased. However, when the elliptical ratios were increased, the energy capabilities increased.
