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.

Exceeding the Forming Limit Curve with Deep Drawing Followed by Electromagnetic Calibration [PDF]
, 2012 We show that the materials quasi-static forming limit curve (FLC) can be exceeded by the process chain composed of deep drawing followed by electromagnetic forming. We form circular cups as close as possible to the FLC by deep drawing.

INVESTIGATION INTO REASONS FOR MINIMUM MAJOR STRAIN OFFSETTING OF FORMING LIMIT CURVE OBTAINED WITH NAKAJIMA TEST FOR AA 2024-T4 [PDF]
, 2014 In a typical forming limit curve (FLC), the minimum major strain where the minor value is equal to zero is located at y axes. In many forming processes, failure occurs at this region.

Investigations on the Formability of Incremental Punching Process
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2011 It was reported that the incremental sheet metal forming (ISMF) produces larger deformations as compared to the conventional forming processes. We developed a new ISMF method based on incremental punching. In this study, a theoretical method based on M-K

Application/Comparison Study of a Graphical Method of Forming Limit Curve Estimation for DP590 Steel Sheets [PDF]
한국정밀공학회지, 2019 Since its introduction, the Modified Maximum Force Criterion proposed by Hora et al., has been widely used to theoretically estimate the forming limit curve of metal sheets. On the basis of this criterion, a graphical method was presented in our previous
