Abstract The fracture resistance of different advanced high-strength steel (AHSS) sheets for automotive applications is investigated through conventional tensile tests, toughness measurements, and hole expansion tests. Different fracture-related parameters, such as the true strain (TFS), thickness (TTS), at crack initiation ( w e i ), specific essential work ratio (HER), are assessed. ) shown t...

INTRODUCTION Woven textile structures are often used as reinforcements in composite materials. Their ease of handling, low fabrication cost, good stability, balanced properties, and excellent formability make the use of Woven Fabrics (WF) very attractive for structural applications in, for example, the automotive and aerospace industry. However, due to the process of draping the fibre orientati...

Ti and Ti alloys have been widely applied to biomedical and dental fields and the demands for their applications have increased gradually in these fields. Ti and its alloys have been used as biomaterial because of their high corrosion resistance, low toxicity, low elastic modulus and low density. Their defects are low shear strength, low wear resistance, low weldability, low formability and low...

light-weight and high strength alloys such as al-mg alloys are used in order to reduce the weight of industrial components. however these materials should be formed at elevated temperatures due to their poor formability at room temperature. hot metal gas forming is one of the high-tech forming processes that is used to solve this problem. recent investigation on tube hydroforming showed positiv...

Dual-phase (DP) steels are widely used in sheet metal stamping. However, they typically characterized by low hole expansion ratios. Since flanging is very often applied to parts, solutions for improving flangeability needed. In this study, high-speed punch rotation of DP 1000 generate frictional heat and increase formability. The flanges were formed using a rotating at 8000 rev/min varying axia...
