In this study, experimental and numerical analyses are conducted to investigate sheared
edges after trimming three automotive sheet metals including TRIP steel, hot-stamped (HS) …

To select a rational method for cutting of rolled stocks made from materials with different
physical and mechanical properties, an engineer must have the tools to make such a choice …

A new method of upsetting the workpieces with conical ledges has been proposed and
investigated in the paper. A workpiece's relative height before upsetting was H/D= 3.0 …

The work aims to improve the quality of workpieces obtained by breaking rolled stock
products by researching the separation process under dynamic and static-dynamic loading …

Lean-burn swirl stabilized combustors represent the key technology to reduce NOx
emissions in modern aircraft engines. The high amount of air admitted through a lean-burn …

In this thesis, the results of an experimental analysis of blanking angled hooks with a punch
of a sloping face in a thin steel sheet with a hardness of 55 HRC are presented. The …

Two DP 980 steels were characterized with multiple methods to determine its microstructure
characteristics, tensile properties and edge stretchability. The first (DP980-B) is a …

Die clearance is a widely known parameter affecting both tool life and edge quality of parts
in blanking operations. Selecting the optimum punch–die clearance can give a longer tool …

The blanking/trimming/cropping process introduces a substantial plastic deformation to the
sheet metal and causes premature edge fracture during the subsequent forming process. In …

An integrated finite element-based modeling framework is developed to predict the hole
expansion ratio (HER) of AA6111-T4 sheet by considering the piercing-induced damages …
