heal.abstract	Commercial finite element codes, e.g. the explicit code LS-DYNA, have made significant progress. They have been developed and improved to the point of being able to predict the various crash problems, as well as to successfully simulate the collapse of tubular components with a reasonable amount of computer time, allowing such structural crashworthy elements to be designed and analysed without having to build and test expensive prototypes. The present paper is dealing with the implementation of the explicit FE code LS-DYNA to the simulation of the axial crushing performance of steel and aluminium thin-walled circular frusta with a constant nominal axial length and various semi-apical angles and wall-thickness. The obtained numerical results are compared with actual experimental data from small-scale models and useful concluding remarks pertaining to the design requirements of the crushing process are drawn. © Woodhead Publishing Ltd.	en
