Application of Two Advanced Vision Methods Based on Structural and Surface Analyses to Detect Defects in the Erichsen Cupping Test [PDF]
Archives of Metallurgy and Materials, 2019 Due to the wide range of various sheet metal grades and the need to verify the material properties, there are numerous methods to determine the material formability. One of them, that allows quick determination of sheet metal formability, is the Erichsen

Material and Damage Characterization of the Elastoplastic Response of the EK4 Deep Drawing Steel
Metals, 2022 Although EK4 drawing steel is nowadays widely used to manufacture a great variety of parts, it exhibits a marked normal and planar anisotropy that can make it difficult to control the process during its forming.

3D Molding of Veneers by Mechanical Means
BioResources, 2014 The 3D moldability of veneers, as opposed to the moldability of plastic or other materials, is limited because of the characteristics of wood. By mechanical treatment under appropriate conditions, it is possible to partially modify veneer characteristics.

Modification of Veneers by Lamination and Steaming for the Purpose of Increasing 3D Moldability
BioResources, 2014 The focus of this work was to determine the 3D moldability of veneers on circular test pieces treated with steam plastification. These results were compared with results acquired from pieces laminated with three different types of laminating foils with ...

EXPERIMENTAL FLC DETERMINATION OF HIGH STRENGTH STEEL SHEET METAL
Acta Metallurgica Slovaca, 2015 To assess formability in sheet forming, experimentally determined Forming Limit Curves (FLC) are often used. These conventional FLCs represent the forming limits (i.e.
