In this paper, the energy absorption features of tri-layer explosive-welded deep-drawn cups subjected to quasi-static axial compressive loading are investigated numerically and experimentally. To produce the cups, tri-layer blanks composed of aluminum and stainless steel alloys were fabricated by an explosive-welding process and formed by a deep drawing setup. The quasi-static tests were carrie...

Due to the high strength weight ratio and ability form desired shape, AA2017 is extensively used in automobile industry. The join with other aluminum alloys capability respond heat treatment creates opportunities for engineers AA6061 blanks using friction stir welding. Controlling process parameters a challenge optimization of tool pin geometry, axial force, rotational speed, welding tilt angle...

Tailor-made blanks are sheet metal assemblies with different thicknesses and/or materials and/or surface coatings. A monolithic sheet can be machined to make the required thickness variations that is referred as tailor machined blanks. Due to the thickness variation in tailor machined blanks, laser bending of these blanks is more complicated than monolithic plates. In this article, laser formin...
