Experimental And Theoretical Determination Of Forming Limit Curve
Archives of Metallurgy and Materials, 2015 The paper presents a method for determining forming limit curves based on a combination of experiments with finite element analysis. In the experiment a set of 6 samples with different geometries underwent plastic deformation in stretch forming till the ...

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.

Uniformity of thickness of metal sheets by patchwork blanks: potential of adhesive bonding
Fracture and Structural Integrity, 2020 The sheet metal forming operations generally involve the production of parts characterized by a non-uniform thickness distribution. However, in some cases, a product characterized by a distribution of thicknesses that is as uniform as possible may be ...
