Forming limit indicators in metal forming [PDF]

, 2011
Precise information on forming limit indicators is very important in designing the technological processes of metal forming. The significance of stress state and strain history for limit strains realization is emphasized above all.

Forming Limit of Holed Dome in Two-Stage Stretch Forming

, 2010
This paper deals with the accurate prediction of forming limit of a dome with a circular hole in two-stage stretch forming. Since this two-stage forming is a process of non-proportional deformation, a fracture criterion, which is capable to predict ...

Implementation of a pressure and rate dependent Forming Limit Diagram model into NIKE and DYNA [PDF]

, 1995
The Forming Limit Diagram (FLD) has been used for decades as an aid to successful sheet metal forming. In this work, we describe the incorporation of the FLD technique into the DYNA and NIKE codes at LLNL along with applications that led to the ...

Formability of AA7021-T4 Sheet Alloy Under Changing Strain Path Conditions: Experiments and Crystal Plasticity Modeling

Crystals
The formability of AA7021-T4 sheets under changing strain paths was investigated via a novel crystal plasticity model and associated experimentation. The motivation was to advance simulation tools for process design of limited-ductility 7xxx alloys, with

Development of Stress-Based Forming Limit Curves for Predicting Crack Occurred during Deformation of UHSS DP980’s Parts [PDF]

Unless the strain-based forming limit diagram (e-FLD) is a useful tool in failure prediction for sheet metal, the complex shape can lead to a non-linear strain history, which e-FLD cannot adequately describe.
