Filleting four corners of square tubes is suggested to reduce the peak force and improve energy absorbing performance. Three-point bending tests are conducted to investigate fillet radius effects employing an ABAQUS explicit code. Three cases characterized by the ratio of width to thickness are considered. Fillet greatly reduces the maximum forces compared with square cross-sections, and the normalized maximum forces decrease with increasing wall thickness when the fillet radius is larger. Additionally, the fillet dramatically improves SEA (Specific Energy Absorption). The normalized CFE (Crash Load Efficiency) significantly exceeds that of the square ones, and the normalized CLE s are almost identical with the increasing fillet radius.

“…Kim and Reid [14] proposed a kinematically admissible analytical model based on the Kecman's and Wierzbicki et al's models. Huang and Lu [8] further studied Kim and Reid's model by using finite element (FE) models. Usually, the bending collapse of thin-walled members is localised at plastic hinges and the remaining parts of the column rotate as rigid bodies.…”

Composite inserts are a well-known and innovative technology in the automotive industry used to improve safety, NVH (noise, vibration, and harshness) and fatigue life of vehicles, as well as to reduce vehicle weight and manufacturing cost. In order to study the crashworthiness performance of composite inserts in a vehicle structure, a three-point bending test of simplified steel-composite combined beam structures is considered. The beam structure in this investigation has a double-hat section. Epoxy-based structural foam and 33% short glass fibre reinforced nylon insert are considered as composite fillers for the two empty beam sections. Four cases, based on the different combination of composite materials inserted in the beam sections, are considered. The test results show that the composite insert greatly contributes to improvement of the energy absorption of beam structure. The force-displacement (F-D) curves of bending tests, the deformation behaviours of beam structures and the failure modes of composite inserts are shown and analysed to understand the effects of composite inserts to the crashworthiness of the beam structure in a bending condition. The numerical study was performed to develop a practical finite element (FE) model of the steel-composite combined structure.
