Recently, origami structures have been widely studied for various applications such as
mechanical, electrical, bio, and nanosystems. Unlikely paper-like materials, engineering …

This paper focuses on the effect of the die and punch radii on the springback in the air V-die
free bending process of stainless steel sheet metal. The experiment was performed on sheet …

In this study, experimental and numerical approaches are used to investigate the effect of
pre-punches on the spring-back of U-channels made of St12 with 1-mm thickness. Three …

Spring back is the most important phenomenon that affects the accuracy of the sheet metal
parts. the important problem because spring back is major forming defect in sheet metal …

Origami-based sheet metal (OSM) bending is an extension of rigid origami technique, where
the final 3D structure is created from a single 2D flat pattern by bending. The key aspect of …

Springback is a geometrical defect that occurs due to the removal of the bending force acting
on the component the end of the forming process. In the present study, springback behavior …

A V-bending experimental setup has been designed, to analyze the impact of blank
geometry and process parameters over the springback in hot-rolled high-tensile-strength …

A small hydraulic press for V-bending operation is designed, manufactured and modeled.
The hydraulic bending press consists of hydraulic circuit, punch, die and PLC control unit …

Today, die design standards are used to design the structure of die components. These
standards are usually based on high safety factors. So, the die components are often …

The influence of considering the variations in material properties was investigated through
continuum damage mechanics according to the Lemaitre isotropic unified damage law to …
