Abstract:This paper addresses the energy absorption behaviour and crashworthiness optimisation of short length circular tubes under quasi-static lateral loading. Finite element (FE) models were developed using implicit FE code ANSYS to simulate the deformation behaviour and energy absorption of circular tube under lateral loading.These FE models were validated using experimental techniques to ensure that they can predict the responses of circular tube with sufficient accuracy. Response Surface Methodology (RSM) for design of experiments (DOE) was used in conjunction with finite element modelling to evaluate systematically the effects of geometrical parameters on the energy absorption responses of laterally crushed circular tubes.Statistical software package, Design-Expert, was used to apply the response surface methodology (RSM). The energy absorbing responses (specific energy absorbing capacity (SEA) and collapse load (F)) were modelled as functions of geometrical factors (tube diameter, tube thickness, and tube width). These developed functions allow predictions of the energy absorption response of laterally crushed tubes, based on their geometry parameters. Based on DOE results, parametric studies were conducted to generate design information on using the laterally crushed tubes in energy absorbing systems. Finally, the approach of multi-objective optimization design (MOD) was employed to find the optimal configuration of the proposed energy absorption structures.Design-Expert software, which employs the desirability approach as optimization algorithm, was used for solving the MOD problem.

“…When the cross-section is changed or combined the behavior of the tube also changes [1], therefore it is a herculean task for designers and engineers to find out the best configuration for a circumstantial exercise. Due to individualize characteristics of the different cross-section, numerous probe is conducted by researchers including rectangular, hexagonal, triangular, pentagonal, octagonal, 12-sided star, 16-sided star, lateral corrugations to name a few [2][3][4][5]. Z. fan conducted quasi-static axial compression test on thin-walled tubes with different cross-sections.…”

“…After a literature survey, we realized that many Authors have considered the load-carrying capacity of polygonal section, even though in most cases the reference problem was represented by axial load only (see e.g. [1], [2], [3]). The basic formulation for local buckling due to bending can be retrieved in the classical textbook [4], which reports the stability assessment for elastic plates rigidly jointed along their edges, in order to obtain open and closed thin-walled profiles.…”

Abstract. The present paper is focused on the development of an accurate computational method, based on the Finite Element (FE) approximation, for predicting the collapse behavior of thin-walled polygonal steel beams subject to bending. The numerical model has been created using the software ABAQUS, and has been validated with experimental data obtained from the literature, concerning rectangular hollow section (RHS) in the four
