INVESTIGATION INTO REASONS FOR MINIMUM MAJOR STRAIN OFFSETTING OF FORMING LIMIT CURVE OBTAINED WITH NAKAJIMA TEST FOR AA 2024-T4 [PDF]
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
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]
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

Ellipticity loss analysis for tangent moduli deduced from a large strain elastic–plastic self-consistent model [PDF]
In order to investigate the impact of microstructures and deformation mechanisms on the ductility of materials, the criterion first proposed by Rice is applied to elastic–plastic tangent moduli derived from a large strain micromechanical model combined ...
