The springback in the sheet metal forming process refers to the change of shape after the load removal. It is usually undesirable, causing problems in the subsequent forming operations, in the assembly and negatively affects the quality of the final

Numerical simulation is an important tool which can be used for designing parts and production processes. Springback prediction, with the use of numerical simulation, is essential for the reduction of tool try-outs through the design of the forming t

This contribution focuses on examining properties of thin steel sheets, which have been used to produce packages. Thin steel sheets for producing packages have been created with a different method (considering their thickness) than other thin steel s

To assess formability in sheet forming, experimentally determined Forming Limit Curves (FLC) are often used. These conventional FLCs represent the forming limits (i.e. onset of necking) of a sheet material subjected to in-plane deformation or almost

During cutting, there is a plastic deformation in the cutting area and subsequent hardening of material occurs in this area. The hardening of material in the cutting area causes a change in its mechanical properties, which also has an impact on the p
