| Abstract | This paper presents the material properties of both cold-formed and hot-finished elliptical hollow sections. The material properties of the elliptical hollow sections caused by different formation processes are investigated. Tensile coupon specimens extracted from different locations across the cross-sections were tested. The mechanical properties of the cold-formed and hot-finished elliptical hollow sections, such as the initial Young’s modulus, 0.2% proof stress (yield stress), ultimate tensile strength, strains at ultimate strength and fracture as well as Ramberg-Osgood parameter that describe the shape of stress-strain curve, were obtained. The mechanical properties of the cold-formed elliptical hollow section obtained from the coupon tests were compared with those of the hot-finished elliptical hollow section. In addition, residual strains in the cold-formed and hot-finished elliptical hollow sections were also measured. The strain measurements involved both the longitudinal and transverse directions across the cross-sections, and the residual strain distributions in the cold-formed and hot-finished elliptical hollow sections were plotted. In this study, the test data obtained from the tensile coupon tests and the residual strain measurements for both cold-formed and hot-finished elliptical hollow sections are valuable information for future analytical, numerical and theoretical studies on elliptical hollow sections. |
