Digital image correlation (DIC) analysis methods can provide very accurate strain
measurement that is useful for identifying the onset of localized necking and thus …

Electrohydraulic forming is a pulsed metal forming process that uses the discharge of
electrical energy across a pair of electrodes submerged in fluid to form sheet metal at high …

A multiscale modeling approach is used to predict how the formability of dual-phase (DP)
steels depend on the properties of their constituent phases and microstructure. First, the flow …

Dual phase (DP) steel sheets are increasingly being used for automotive applications due to
relatively high strength and formability. In the current work, Marciniak formability tests were …

In this paper, a new method for determining the forming limit diagram (FLD) of thin sheet
metals, called DIC-Grid method, is proposed based on digital image correlation (DIC) …

Higher strength advanced high-strength steels (AHSS) such as DP780 and DP980 are more
susceptible to fractures at bend radii during press stampings in comparison with more …

Forming limit curve (FLC) and fracture forming limit curve (FFLC) are valuable tools for
failure prediction in forming simulation and die try-out in press shops. In this paper, methods …

For the past decades, the adoption of empirical equations in the forming limit curve (FLC)
calculation for conventional steels has greatly simplified the forming severity assessment in …

New generations of advanced high strength steels (AHSSs), expected with tension strength
exceeding 1000 MPa, sufficient cold-stamping ductility, and low-alloyed microstructure, are …

A methodology for stress-based forming limit analysis has been developed for advanced
high strength steel (AHSS). It was proposed that localized necking occurs when a critical …
