Crashworthiness Design Using to Investigation of Axial Crushing Behaviour of Axsisymmetric Tubes

Designing and studying the energy absorption behaviour is one of the important subjects in the industries. The thin-walled metal tube structures are one of the most widely used types of energy absorbers that have always been considered by researchers for predicting how to crushing behaviour and dete...

description	Designing and studying the energy absorption behaviour is one of the important subjects in the industries. The thin-walled metal tube structures are one of the most widely used types of energy absorbers that have always been considered by researchers for predicting how to crushing behaviour and determine the amount of energy absorbed by them. A numerical study of crashworthiness design using to investigation of axial crushing behaviour of axisymmetric tubes is presented in this paper. First, a Finite Element (FE) model for material properties was constructed and validated by experimental data. Next, a model for the thin-walled tube under axial loading was adopted. The comparison between the FE results as well as the experimental results showed good agreements. The validated FE model was then used to investigate axisymmetric thin-walled tubes with different cross-section and parametric studies of best geometry under axial loading. Making a totally 7 different geometries and the collapse behaviour of the absorbent geometries then has been simulated. A comparison of energy absorption results and maximum crushing load between the different geometries show that conical tubes with shallow spherical caps are better than others.
