Affecting the Determination of Forming Limit Diagram for Sheet Metals
The sheet metal forming is defined as the ability of metal to deform plastically (stretch forming) without necking or fracture. To control the sheets forming operation failure a diagram is used , in which the ; accepted forming , failure and critical ...

The Forming Limit Diagrams of a Brass Sheet
The forming limit diagrams of proportionally pre-strained brass sheets are experimentally determined for a combination of uniaxial and equi-biaxial tension. From these FLDs and the theoretical ones which are predicted by the use of a new plastic constitutive equation previously proposed by one of the authors (Gotoh) and a local necking condition, the ...

Experimental and Numerical Analysis of Prestrain on the Formability of Zn-Cu-Ti Alloy Zinc Sheet
The forming limit diagrams (FLDs) characterizing the formability of sheet metals are usually obtained by applying proportional loadings. Nevertheless, the industrial processes involve strain path changes that can modify the limit-strain values.
