Bending of cylindrical steel tubes: numerical simulation using grid computing

Crashworthy structural elements may be subjected to various types of loading, such as axial or lateral compression and bending; consequently, extensive theoretical and experimental research work has been performed exploring the collapse mechanisms occurred under such loading conditions. However, the designer needs theoretical tools ranging from simple analytical calculations to full finite element analysis using non-linear, large deformation codes. The main objective of this paper is to apply the explicit FE code LS-DYNA through a grid computing platform in order to simulate the crash behaviour of thin-walled cylindrical steel tubes subjected to three-point bending test in various cases of the position and direction of the imposed load. The simulation has been carried out through the GRIA computing platform that advances the computational performance of the executed tests, and additionally enables the remote and collaborative conduction of the experiments. The results taken from the simulation allow in drawing useful concluding remarks pertaining to the design of the crushing process.
