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